Message from the PSMA Executive Committee

 

Without a doubt we are approaching the end of a quite different and challenging year not only for our organization but also for all our member-companies and individuals who support, participate and volunteer for PSMA.  As the world and businesses continue adjusting to a new pandemic-imposed reality, PSMA not only confronted the challenges, but with creative and agile support of its numerous volunteers, the dedicated people who run the office, the board and the executive committee,  co-sponsors and partners responded with agility and creativity to minimize financial loss and risk, while maintaining the valuable services to its members and the community.

We at the executive committee are excited to implement and work in alignment with the newly adapted four pillars of our organization: (i) build on strengths, (ii) become more applications oriented, (iii) integrate performance metrics to assure value add to our community, and (iv) engage with the stakeholders.  Using these guidelines, we hope to drive success and growth of a more vibrant, more active, and more relevant PSMA.

As the member of the executive team who champions the third pillar, the implementation of key performance indicators throughout the operations and activities undertaken by PSMA, I hope to establish a measurable understanding of the "value-add" to "asset allocation" ratio in order to prioritize and improve the effectiveness of our efforts and resources.  Ahead of us is another financially challenging year and this task is critical for sustaining short- and long-term financial viability.

Some of the areas that we plan to implement performance metrics so that we can better understand impact on growth and revenue include:  membership movement comparable to the number of professionals in the industry, web activity tracking, differentiation and consumption of PSMA exclusive offerings such as special projects, reports, databases and other contributions as well as feedback received on our activities. 

We also plan to apply these metrics to activities related to popular workshops and webinars to maximize the value to our members and the wider power electronics industry, return on investment and exposure for PSMA. Remember, as a not for profit organization of volunteers, we need to spend our income from memberships, studies, and events prudently and maximize the use of in-kind human capital from our volunteers. We hope to expand the key performance indicators across the whole organization for example to support and help optimize the numerous committee efforts so as to attract more participation and increase activity.

The Executive Committee will not be able to establish, build and strengthen the performance metric pillar to become an impactful potency without the support and the collective effort of all the members and the volunteers of our organization.  We are encouraging all of you on an ongoing basis to provide feedback, thoughts, and new ideas as we continue to grow a successful PSMA.

Please feel free to contact me or any of the executive team members or the PSMA office anytime. We would love to hear from you and need your inputs!

Trends within The Power Electronics Industry in 2022

As is the case in many industries, power electronics has been impacted by the Covid-19 pandemic. This includes a boost in new technologies and opportunities for power designers to capitalize on the benefits of E-learning. While it is always difficult to derive trends from large industries, as we get closer to APEC 2022, as a power engineer it is interesting to take a minute to ponder and consider what will contribute to making power supplies more efficient, more reliable and exciting to design.

Overall trends and technology
A major trend that we are all aware of is the 'electrification' and transition from fossil fuels to renewable energy. There are a lot of technological innovations required in this segment to reach the carbon neutral level expected by the European Commission, US DOE and similar initiatives in Asia. If we focus on what most of the power supplies companies are developing, I foresee that four trends, all of which will benefit from the implementation of Wide Band Gap Semiconductors, will influence the power industry in 2022:

  • Reducing energy consumption
  • Power supplies becoming part of the Machine-to-Machine eco-system
  • Enhanced energy storage solutions
  • Acceleration of harvesting energy solutions,

In the quest for reduced energy consumption, from harvesting energy to the grid, the power electronics industry is seeking new long term solutions to improve efficiency. International and local regulations have already forced power supply manufacturers to innovate, and we are seeing more stringent regulations under discussion that would require the power industry to further explore new topologies, components and materials.

One example that illustrates and will benefit from this trend is E-commerce.

E-commerce was already growing before Covid-19, but as consequence of curfews, working at home, and the drastic reduction of physical interaction, it has grown exponentially, putting a high demand on shipping hubs, computerized storage and the overall supply chain. Before we even mention the associated datacenters required to manage the E-commerce process, there are the shipping hubs and warehouses that have become gigantic and consume lots of energy. Making these hubs more energy efficient has been on the agenda for all the major players, and the 2020-2021 peak on demand was a strong a signal for the need to reconsider the way to use and to manage energy.

Power supplies as such are not consuming the majority of this energy, but, when one considers their strategic position in the operational chain, they become a key point in the overall process to optimize how energy is used in the complete chain. In 2022 we will see very advanced power supplies used in E-commerce handling and shipping hubs. Not only will they integrate higher levels of communication, they will also be able to store and restore energy from supercapacitors banks, reducing peak disturbances on the grid and consumption. Already experimented with in 2021, the power supplies have been integrated into a complete eco-system with Machine-to-Machine communication (Figure 01). They not only deliver power to a load e.g. conveyor motors, but they are able to sense and adjust the level of energy to store in local supercapacitors bank (Figure 02).

Almost invisible, from the RFID inserted in the shipping box that will get power from RF signals, to sensors placed on motors or moving elements powered by vibration, micro-systems powered by harvested energy are developing very quickly. Additionally, the nanotechnology, such as nanotubes, make it possible to develop very small supercapacitors able to store enough energy to power sensors and transmitters.

To make this possible, the implementation of digital power and communication is a must, but the level of performance will also require power electronics engineers to design new power solutions with the so called 'Wide Band Gap' semiconductors. Depending on the application and voltage required they may select GaN or SiC types, but the benefits of WBG will contribute to making E-commerce more energy efficient and to reducing the carbon footprint.

Critical building blocks!
For decades the improvements in energy efficiency levels of power supplies have been made possible by technological evolutions. Moving from linear to switching technology was an early major one, followed by a number of more minor leap-frogs until digital power came to market.

Despite it having been on the market for several years, with the emerging WBG technology and the possibilities offered by those components, digital control becomes an absolute MUST and I strongly believe it will be a major building block for power designers when developing new products.

For components, the WBG transistors are without doubt the ones that will prevail in 2022. That said, conventional Power FETs are also making big progress and power designers will have to achieve new levels of business assessment and acumen when selecting the most appropriate technology for their applications.

advanced digital control and GaN FET transistors (Source PRBX)

The third building block I foresee as important is the advanced planar transformer with interleaved multi-core technology. Not all power supplies require megahertz switching but considering the constant quest for smaller power supplies with higher efficiency, power designers will have to consider new types of transformers and new winding techniques. In that respect they will not only be helped by ferrite manufacturers developing new materials but also by Artificial Intelligence software that can shorten the time to design and test new transformer types (e.g., Frenetic, Simba).

One specific example of this is research currently being conducted at PRBX, combining digital control, GaN, and multicore transformers with advanced wiring and auto-tuned performance within the wide operational range that is seen in some industrial applications that require extremely wide input voltage ranges, as well as outputs subject to repetitive peak loads. Final products while not ready yet will not be possible without the combination of digital control, WBG and advanced magnetics (Figure 03).

I believe many of the new products that we will see in 2022 and onwards will be based on these three building blocks, which I'm sure will also include more communication to become part of a Machine-to-Machine ecosystem.

In WBG we trust!
One interesting aspect about Wide Band Gap semiconductors is that we are seeing a similar situation to when the first power MOSFETs were launched. Some immediately considered the benefits of the WBG, despite early products that were based on a depletion mode that required very specific drivers  and were not very user friendly, it didn't take too long for power semiconductors manufacturers to provide 'easy-to-use' solutions.

It has now been more than five years since manufacturers first promoted the benefits of that technology but if the Go To Market is ready, the Go To Application for mass users still requires a certain amount of time.

We are all familiar with the 'camel-back' curve reflecting new technology adoption and crossing the chasm. Experienced power designers have crossed that technological chasm many times, with the latest one being the migration from analog control to digital, which took more than 10 years to reach a significant level of adoption (Figure 04).

In the case of WBG, and especially Gallium Nitride (GaN), early adopters entered the fray much quicker than some had predicted a few years ago. It is no surprise that the PC and Mobile/Nomad industries were some of the early adopters. The number of USB-C chargers using GaN semiconductors announced in 2020-2021 is very impressive. Particularly worthy of mention is Navitas' next-generation GaNFast power IC that will drive the 120W ultra-fast charger supplied 'in-box' with vivo's iQOO-brand flagship iQOO 9 Pro mobile phone, demonstrating the rapid adoption of GaN by the 'nomad' industry. But it is not just the electrical performance, using GaN also reduces the physical size by 26%, reaching a stunning 1.3W/cc power density, which is quite incredible (Figure 05).

While it took 10 years for digital power to become a de facto technology, it took only five years for WBG to reach a similar level.

What is interesting in the development of the WBG semiconductors is that due to the specificity of this technology, with very low internal resistance and the ability to switch very fast, the packaging is very important and we see a lot of innovation from manufacturers to offer optimized solutions. Technologywise the Efficient Power Conversion (EPC) approach is very interesting, minimizing interconnection losses, and making it possible to shrink a power converter to an unprecedented size (Figure 06).

Of note is the amazing number of technical webinars held during the Covid-19 era, not to mention the virtual APEC 2021. Many companies have taken that as an opportunity for their power designers to attend online training, and as a result some power-semiconductor companies have reported shipping up to 10 times more evaluation kits than before the pandemic days.

If we simplify the market into two segments: High voltage (using SiC) and Low voltage (using GaN), we see two different patterns. High voltage applications such as electric vehicles and solar are already familiar with SiC transistors, and for that segment it is no big revolution for power engineers to undergo a learning phase for the relatively new low voltage technology.

In conclusion
In many different ways we have all been affected by the pandemic, although looking back it has contributed to a boost in learning new technology and speeding innovation. Considering all of that, 2022 will be a very important year for WBG and we can expect many new power supplies (AC/DC and DC/DC) to be announced during the year. 2022 will be a very exciting year for all of us designing power solutions.

International Awards for Tyndall's MagIC Technology

Professor Cian Ó Mathúna recognized for his leadership

Professor Cian Ó Mathúna with the 2021 EARTO Innovation
Award for Impact Expected

 

One of PSMA's long-time contributors and supporters, Professor Cian Ó Mathúna, from Tyndall National Institute in Cork, Ireland has been recently named the recipient of two major international awards celebrating innovative technology created in Ireland, which could have a lasting environmental impact.

Minimizing energy consumption in electronics continues to be a major, technological challenge. Responding to this challenge, Cian, who is currently Head of MicroNano Systems at Tyndall, has, over the last 27 years, developed MagIC (Magnetics on Silicon), an innovative technology that can greatly extend the battery life of portable electronics and dramatically reduce the energy use of high-performance electronic systems and equipment.

The ground-breaking impact of the technology has been recently recognized with prestigious awards from the 400,000 member IEEE (Institute of Electrical and Electronics Engineers) and EARTO (European Association of Research and Technology Organisations).

The IEEE Power Electronics Society Technical Achievement Award for Integration and Miniaturisation of Switching Power Converters celebrates Cian's extraordinary, global influence and leadership over the last decade in bringing together the electronics industry and academia to collaborate toward the development of the Power Supply-on-Chip (PwrSoC).

Tyndall is the first Irish recipient of an EARTO Awardwhich recognizes key contributions from European research to high-impact, technological innovation. The 2021 EARTO Innovation Award for Impact Expected looks to the future and recognizes the impact Professor Ó Mathúna's research will have on the technology of the future. Including dramatically reducing system energy consumption, extending battery life and reducing the overall size, weight and cost of future electronic systems.

Tyndall's MagIC technology makes bulky magnetics components in electronic equipment to disappear onto the silicon chip, just like Gordon Moore and colleagues did with the transistor over 50 years ago. Using MagIC technology, electronics will be able to use power more efficiently by minimizing the energy wasted or lost as the battery powers the multiple-voltage rails required in multi-core microprocessor chips and/or other complex SoC chips. This improved efficiency can extend the charge time of batteries by more than 50%. The breakthrough technology will have a huge impact on markets for mobile phones, IT equipment, and any device needing a battery. It is also envisaged that the technology will deliver significant energy savings in servers in the data centre and high-performance computing space.

Professor Ó Mathúna said, "This ground-breaking and disruptive innovation is set to change the global approach to how power is managed in electronic devices and will contribute to addressing a critical environmental issue for society and our planet. We continue to partner extensively with global companies to develop and commercialize the technology which has already received more than €20M in funding from research, licensing and productization. We have joint publications with companies such as Global Foundries in Dresden and Singapore; Intel, USA; Philips in the Netherlands, TI in the USA; Wurth Electronics in Germany as well as a joint patent with Apple Computers."

Cian joined the November 2021 PSMA Board of Directors meeting and was very gracious and effusive in acknowledging the influence PSMA has had on the emergence of PwrSoC over the last 3 decades. Cian mentioned that he was first introduced to PSMA by Don Staffiere who managed to convince one of his Irish clients, Gary Duffy, then MD of Computer Products (later Artseyn Technologies) to fund Cian's attendance at the 1994 APEC. Cian came to APEC with a very limited background in power electronics but, through Don's introductions to PSMA, he began participating in the PSMA Technology Roadmap initiative, and was quickly able to leverage his expertise in microelectronics packaging which was just beginning to have a very positive impact on the miniaturization and integration of power electronics products.


Joe Horzepa, Gary Duffy, Arnold Alderman and Cian Ó Mathúna at APEC in the mid 2000s

With the support of Don Staffiere, Bob Huljak, the late Prof. William Sarjeant and the strategic guidance and wisdom of Joe Horzepa (and Judy!), Cian engaged with Arnold Alderman and Doug Hopkins to run the Packaging Technical Committee with Brian Narveson and Ernie Parker later contributing their expertise. Around 1997/98, PSMA awarded NMRC (National Microelectronics Research Centre – the precursor to Tyndall) funding to undertake a special project on the state-of-the-art in commercial 3D power electronics packaging and followed this, in 2006/2007, with funding, for Tyndall and Anagenesis, on the very first study on fully-integrated power – the visionary and seminal "PSiP2PwrSoC" project.

Looking back, Cian sees this project as the inspiration for him to establish PwrSoC, the International Workshop on Power Supply on Chip which was first held in Cork in 2008 with over 100 international participants. At PwrSoC2010, Tyndall agreed to hand over the workshop to PSMA and the IEEE Power Electronics Society from which point the Workshop has become recognized as the flagship technical forum worldwide for both industry and academia to get together to discuss both the technological and business challenges and opportunities for PwrSoC.

In his closing remarks, Cian commented "the vision and strategic perspective of PSMA, over the last 27 years, has had a dramatic impact on seeding research in power electronics, on providing a dedicated forum to gain insight into major power industry challenges and, in particular, in providing me, and the wider team at NMRC/Tyndall, with the international perspective to succeed. For all of this, I am forever in PSMA's debt."
