APEC Returns to Long Beach for 2024

APEC 2024 in Long Beach - Back to Pre-COVID Energy and Attendance

A PEC 2024, in Long Beach next February, is truly back to pre-COVID activity. Following the unfortunately-late cancellation of APEC 2020 in New Orleans and the need to accommodate the pandemic-mandated restrictions in the years following, our 2023 event in Orlando was the first to show a return to the conference's constant year-on-year growth. Never has power electronics been more in the forefront of electronics design and packaging and APEC 2024 is sizing up to be bigger than it's ever been. A full two months before registration opens in October, the booth space in the exhibit hall as already sold-out! The conference planners are working to see about adding more space to the exhibit hall to accommodate the growing waiting list of exhibitors.

The APEC 2024 Conference committee has been working diligently to prepare for the event that will be held a month earlier next year than has been the case for over a decade.  While it's just a bit too early to report on the specifics, I can report that Professional Education Session, Technical Session and Industry Session programs are coming together and will provide attendees with a full slate of career-enhancing information and insights. Registration will open in mid-September and the fee for full conference registration (still one of lowest of all IEEE conferences) includes free access to the Sunday and Monday Professional Education Seminars as well as a free ticket to the Wednesday evening Social Event.

Remember, you need to register to get access to the discounted hotel reservations. These special hotel blocks will sell out well before February.

As always, APEC includes a lively Exhibition that begins on Monday evening with a hosted reception on the trade show floor. The exhibits are also open on Tuesday and Wednesday and offer a hosted lunch service to attendees.

If you haven't already made plans to attend, don't wait any longer. Be sure you have it in your 2024 budget to attend this exceptional event – truly The Premier Event in Applied Power Electronics

I hope to see you in Long Beach, February 25-29, 2024.

European Ecodesign – Energy Efficiency, What's Next

A s power electronics engineers we have always sought for the highest efficiency power conversion methods, thus minimizing power dissipation and energy consumption. Well before any governmental regulations, the power electronics community has innovated to develop components and topologies that have contributed to saving energy. As energy efficiency regulations have empowered all around the world, further still we have researched into new ways of managing and storing energy but at the same time other environmental parameters have required power electronics manufacturers to integrate Ecological Design (Ecodesign) principles in everything that they do. What will that mean for the power electronics community?

From a Vision to the Ecodesign regulation
From 1866 when Ernst Haeckel established links between living organisms and their surroundings the ecology has been through a number of steps and cycles. Sim van der Ryn and Stewart Cowan's research in their book 'Ecological Design' developed the concept of integrating human activities with natural processes and was aimed at minimizing the destructive environmental impact. This was followed in 2002 by the publication of William McDonough and Michael Braungart's manifesto book 'From Cradle to Cradle', and so a lot of initiatives and projects have taken place to develop a circular economy and to preserve natural resources. One practical example is the 'Ecodesign' framework directive proposed on August 1, 2003 by the EU Commission for energy-consuming equipment [COM(2003)0453].

At a time when many power supply efficiency levels were peaking at 82%, standby power consumption was not considered an issue, and energy management within final equipment not even a concept, the EU proposed to improve the overall environmental performance for energy-using products (EuP), with a focus on energy efficiency but also the environmental impact during the overall product lifecycle.

April 20, 2004: The EU Parliament adopted a resolution on the proposal of an EU Ecodesign framework directive for energy efficiency and other environmental characteristics of products. On July 6, 2005 the proposal became the directive [2005/32/EC], giving two years to applicable countries to implement.

Among a number of products, the directive included external power supplies with a maximum output power of 250W that are intended to work with electrical and electronic household and office equipments [Regulation (EC) No 278/2009]. This directive was updated in October 2019 [Regulation (EU) 2019/1782] and as new technologies are contributing to improved levels of efficiency, it will be revised within a year to add product categories and to adjust threshold values.

Because the EU Ecodesign is very much consumer oriented, a number of activities are supporting them in the choice of buying and using products. For example, an important decision was to make it mandatory for listed products to bear a label indicating the energy efficiency with a comparative scale from the most efficient to least efficient (A to G). Originally created in 1992, and considering technological advances and improved energy efficiency levels, in 2010 the labelling Ecodesign scaling was redefined as A+++ to D and additional information for consumers e.g., noise levels added. The 2010 scaling was confusing and in 2019 the updated labelling regulation reintroduced the original A-G scale, a new calculation method taking real usage in consideration implemented, a QR-Code added [figure 01]. As well, to support consumers, manufactures and retailers, and to ensure a smooth transition from the old labels to the new ones, the European Commission has developed an online database, the European Product Registry for Energy Labelling (EPREL) publicly accessible.

EU Green Deal and Ecodesign
From its origin the EU Ecodesign was meant to cover more than energy efficiency, but the complexity was such that the commission took a wise approach to make implementation smooth and acceptable by the industry and consumers.

In March 2020 the European Commission adopted the new circular economy action plan (CEAP) [COM(2020) 98], which is one of the main building blocks of the European Green Deal [COM(2019) 640]. The goal of the EU transition to a circular economy is to reduce pressure on natural resources and to create sustainable growth and jobs within the European community. It is also a prerequisite to achieve the EU's 2050 climate neutrality target and to halt biodiversity loss.

As William McDonough and Michael Braungart wrote 20 years ago, the circular economy is a model of production and consumption that involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible. In this way, the life cycle of products is extended. In practice, it implies reducing waste to a minimum. When a product reaches the end of its life, its materials are kept within the economy wherever possible thanks to recycling. These can be productively used again and again, thereby creating further value.

This is a distinct departure from the traditional, linear economic model that is based on a take-make-consume-throw away pattern. This model relies on large quantities of cheap, easily accessible materials and energy. Also part of this model is planned obsolescence, when a product has been designed to have a limited lifespan to encourage consumers to buy it again.

The current Ecodesign Directive 2009/125/EC has a long track record of delivering benefits to businesses, consumers and the environment. In 2021 alone, the impact of the current Ecodesign measures, embracing 31 product groups, saved EUR 120 billion in energy expenditure for EU consumers and led to a 10% lower annual energy consumption by the products in its scope, and it was time to expand the directive to include circular economy.

In March 2022 the Commission published a proposal for a new Ecodesign for Sustainable Products Regulation (ESPR). The proposal establishes a framework to set ecodesign requirements for specific product groups to significantly improve their circularity, energy performance and other environmental sustainability aspects. Among the additional requirement we could highlight product durability, reusability, upgradability and reparability, which have been under discussion for more than five years. Open Public consultation took place from January to May 2023 and is now under discussion for an expected adoption during the first quarter 2024.

Ahead of future regulations
Among the additional products to be covered by the EU Ecodesign regulation was a requirements for servers and data storage products [EU Regulation 2019/424]. The objective of the regulation was to limit the environmental impact of these products with a set of rules on energy efficiency, such as the minimum efficiency of power supply units, the minimum server efficiency in the active state, the maximum consumption in the idle state, and information on the product operating temperature. The regulation also takes into account circular economy aspects such as extraction of key-components and of critical raw materials, the availability of functionality for secure data deletion, and provision of the latest available versions of firmware.

Although originally expected to be enforced in January 2023, but due to the ongoing global supply crisis for semiconductor chips brought about by the COVID-19 pandemic resulting in power supplies manufacturers facing longer lead times than initially expected for the delivery of critical components, in December 2022 the Commission issued a notice [2022/C 469/03] postponing the date of implementation to January 2024.

The EU Ecodesign directive for energy efficiency in datacenters is similar to the 80 PLUS, and the level similar to Titanium for single outputs, and Platinum for multiple outputs, whilst noticing that the Power Factor Corrector figure of 0.95 is not defined under the same load conditions [Figure 02].

Considering the increased demand on datacenters relating to the development of Artificial Intelligence, the regulatory commission may consider to strengthen the level of requirements, which power supply manufacturers are taking into consideration by adopting Wide Band Gap semiconductors and new adaptive control methods. Ahead of future regulations, WBG semiconductors manufacturers are already offering reference kits and application support to exceed the 80 PLUS Titanium and EU Ecodesign 2019/424 requirements, e.g., the Navitas Semiconductors CRPS185 [Figure 03].

What will be the next step?
Energy efficiency has been the priority, but as we have said, EU Ecodesign is about developing a circular economy and prioritizing extending product life, making products repairable, reusing as much as possible and changing the way we work from 'cradle to grave' to 'cradle to cradle'. As we presented in 2017 and shared in our white paper 'Will the power supply industry adopt the cradle-to-cradle business model?', we are making good progress and the European Green Deal/Ecodesign will help make things happen.

Make Vs. Buy: OEMs Now Have a Choice for Semiconductors

A   number of years ago I authored an article about the make-vs-buy decision design engineers face in obtaining power supplies for their projects. Due to the ongoing interest in the topic, I recently wrote an update. This article has remained popular because the topic is forever relevant in electronics engineering. System designers are continually faced with the question of whether to make or buy the power supply circuitry they need, while at the same time there are always new options for designing and purchasing power supplies.

Today, some engineers and their companies face a similar question about semiconductors—should we buy them or make them? Here, I have reversed the order of the question because while the default with power supplies was originally for system designers to design and build them, the default with semiconductors has long been to buy them from dedicated semiconductor companies.

However, with large OEMs now having the engineering talent and design tools to create their own ICs, and have them fabricated by foundry companies, make or buy is now a relevant question for semiconductors. The recent unprecedented component famine of 2019 to 2023, which greatly affected the supply of semiconductors, has disrupted supply chains dramatically and cost OEMs millions in lost opportunity. This has driven major companies to take matters into their own hands.

This article looks not so much at the issue of how companies determine whether to make or buy their semiconductors, but rather how trends in the industry are pushing them toward the "make" decision. To understand how the industry got to this point, we need to look back at where the semiconductor business was in decades past and how it has evolved.

The Business Cycles

The semiconductor industry has always been highly cyclical. The first semiconductor cycle I experienced was in 1984 while working as an FAE at Analog Devices. That year, the industry went from normal lead times to 45 weeks to "who knows when?" Subsequent cycles from feast to famine have been the hallmark of the semiconductor industry.

Despite the obsession every semiconductor company has with forecasting, these cycles have continued. Apparently, forecasting doesn't work very well, or we would not have this problem. Or if the forecasts are accurate then semiconductor companies aren't acting on them. Either way, large semiconductor companies, (and I have worked for several) are the most internally focused organizations I have ever seen. Their needs come first, then investors, management and somewhere down the list might be the customers.

In the early days of the semiconductor industry the processes and technologies were internal and as one semiconductor executive once said, "real men have fabs." This was the attitude even as the cost of building and equipping fabs went from multimillions of dollars to multi-billions. Additionally, the top semiconductor companies owned the architectures and processes. So, their value propositions were that they had the fabs and the cores and topologies such as X86, 68000, PA-RISC, and Power-PC. In other words, semiconductor companies owned both the manufacturing and the device IP. 

But then many vertical integrated companies got out of the semiconductor business, as mergers and acquisitions occurred. Moreover, the era of licensed architectures arrived with ARM, RISC-V and others becoming easily obtainable. The barriers to entry in making chips were slowly coming down. Today nobody cares about architecture—just use one of the defacto standards off-the-shelf.

I was present at a famous meeting at Motorola when a major customer arrived for a technology review. They mentioned that they had bought companies who were ARM licensees and wanted to collaborate on IC development using our joint IP. It was a gift from a customer who was looking to do more business with us.

But rather than expressing interest in their offer, our CTO (who had arrived late) stood up and went on a rant that "We, the semiconductor company" would decide on architectures and no architectures that we did not own would be made in our fabs. That was that, and he proceeded to leave the meeting in a huff.

The customer asked who that was and if he was the one who decided such things. After a long pause someone said yes it was the CTO and yes, it was his decision. From the looks on their faces, we could see that the customers were puzzled by this answer and what they heard from the CTO. Perhaps they were thinking how their CTO would not act like a spoiled child throwing a tantrum.

The customers then said that they were not here to ask our permission, they wanted to partner with us and do more business with us. So, if we weren't interested, they would take their business elsewhere. Of course, as a semiconductor company we were still fighting yesterday's war and were hanging onto value propositions that were rapidly going away. Fabs and architectures.

Fast forward to today when we have architectures and modules which one can license without any trouble at all. Additionally, the newer fabs are usually not ones built by semiconductor companies but rather by large contract fab companies and subsidized by governments. The latest downturn caused by a combination of Covid, demand upturn, the Russian invasion of Ukraine as well as other factors caused lead times to go to the max again, for a longer than usual period. This disruption to the supply chain has given customers another reason to avoid their traditional dependence on semiconductor companies and work directly with the fabs.

But they had plenty of reasons to do so before the pandemic. Often being a customer of a semiconductor company is an unpleasant experience. These companies, especially the large ones, can be arrogant and self-centered. Moreover, the larger semiconductor companies have agendas and margin goals, optimizing products for markets and business cases, not individual customers. In short, if you are a customer of a semiconductor company you are a customer, but not the customer.

They have other customers too and of course the investors—Wall Street, who are the real customers. These investor customers have become more important in the modern world than the product-purchasing customers. Among other problems, semiconductor companies can also be unpredictable. They can discontinue parts with little notice, push out lead times, give capacity to more-favored customers and do other unpleasant and unexpected things.

The investors of course want to hear about all the fantastic design-ins and wonderment of Mr. Big OEM's usages. This could result in a cascading failure mechanism for the semiconductor company. For example, sometimes they get bypassed by the large OEM. So, then they cannot write wonderful things about the usages, which drops revenue and stock prices, while the OEM finds they can get by simply fine without them. This means the semiconductor company becomes even less relevant to other large OEMs and so on. This makes things worse of course.

Currently, this discussion of make versus buy only applies to the "gorilla" parts. In other words, SOCs, highly integrated ICs, multicore processors, and perhaps RFICs—the more specialized and complex devices. In other words, the electronics customers can take matters into their own hands by hiring smart designers who might generally prefer to work for the big OEM vs. a semiconductor company, and fab the parts in whatever foundry suits them.

In that case, if you're the customer, you don't have to put up with the dysfunctional semiconductor company's erratic ability to do what you need or deliver products. Your IC can be exactly what you want it to be, it can give you a competitive advantage and you don't have to use a part optimized broadly for a large customer base.

Furthermore, you don't have to put up with the "I need a business case" from the semiconductor marketing teams. If your foundry can deliver, you can cut out the intermediary (the semiconductor company) who might send your fab capacity or parts to another, more-favored customer. And of course, the semiconductor company is keeping a big cut of the margin for themselves.

So, if you are a large electronics company and you just went through years of not being able to get products you need, why would you sign up for more abuse? This is why we see the announcements in the industry publications about so-and-so partnering with "insert foundry name here" to build their latest highly integrated processor and multifunction IC. It gives them the competitive advantages they need to win in the market, and they don't have to put up with suppliers who act like teenagers.

This trend is putting more pressure on the semiconductor companies to find some technologies which are not otherwise available via the foundry partners. Their other option is to hire better, smarter engineers than the OEMs can. However, this isn't necessarily that easy since it might be more prestigious and lucrative for the engineers to work for the significant OEM than for the semiconductor company. It's hard-to-find good talent as evidenced by the ongoing announcements of talent shortages in the industry.

With this talent shortage in mind what are the large electronics companies not going to do themselves? Discrete semiconductors. In general, it's probably not worth it to design and contract the building of small-signal devices and discretes, commodity linear devices, high-function analog ICs, data converters and most specialty RF devices. Also, with integrated modules like Wi-Fi and LTE modules, it's easier to buy those than build them, in part because they need FCC and other certifications that are complex and costly to obtain.

The large electronics companies will be evaluating the design and make-vs-buy based on whether it gives them a competitive advantage, whether they have the needed skillsets to design and make the device and whether they can get the device in question on the open market from several suppliers. Regular power semiconductors and ICs, TVSs, rectifiers, MOSFETS, and regulators such as the LM78xx, LM1117, and LM317 will just be bought from suppliers because no competitive advantages can be obtained by designing and having a foundry build them.

On the other hand, highly specialized PMUs and PMICs that are differentiated, highly integrated and can give a competitive advantage, probably will be designed in-house. FPGAs are probably safe for applications that don't dictate high enough volumes to make a custom IC. As an aside, it's interesting how the large, formerly independent FPGA companies are now owned by major microprocessor semiconductor companies. That was a good way for the microprocessor manufacturers to hedge bets when companies that don't have the volumes for custom ICs need something they can customize without designing and fab'ing their own SOC processor system.

What about WBG devices? SiC an GaN? I simply don't know—we will see. There are foundries for WBG devices too so if the suppliers get fussy it's possible that an OEM could bypass them. You do see major OEMs partnering with WBG semiconductor companies. However, if they don't perform, the next step could be to toss that partner into the weeds, and get a foundry partner who can deliver what they want.

Additionally, the GPU companies are probably safe unless the major electronics companies integrate GPU cores into SOCs or other devices. Perhaps AI will start designing ICs or the AI processors will be integrated into the SOC. It's going to be interesting to see how this develops and I am glad that I am mostly watching from the bleachers.

It's natural to wonder what the semiconductor companies are doing about this loss of business to the foundry companies. You would think there would be a panic with management crying "what are we going to do?" Well, like Polaroid, Kodak, RCA and other industry giants who came before, they seem to be turning a blind eye to the changes. The attitude seems to be "everything is going to be fine, we have been here forever, and we will be here forever."

If the chip makers are concerned, it's not showing. Although I could be wrong and they may be holding internal meetings about future threats and opportunities, my impression is that they are too internally focused for that. Changing the culture of arrogant entitlement is difficult.

Only time will tell how this will shake out. But the foundry companies are not going away, so OEMs will continue to have the option of make versus buy for semiconductors. And when supply chain shortages are a determining factor, as they have been in the automotive industry, it will only push equipment manufacturers more in the direction of designing their own chips and having them built in fabs, removing the semiconductor middlemen.

Semiconductor companies created this customer behavior through their actions, so my thinking is "you broke it, you fix it—if it's not too late". But they probably don't even realize that they caused the customers to explore alternative options in the first place. After all, no single raindrop thinks it's responsible for the flood.

On the other hand, looking at the big picture, it's probably just the natural course of the industry. Years ago, electronics companies were vertically integrated to the extent that they made their own PCBs, chassis and enclosures. Now they simply design or specify them and have their PCBs made and populated elsewhere as are other mechanical parts. Perhaps customers designing their own chips is simply the next step in this process.
