Since 1981 contract research work has grown, encompassing microelectronics and many related fields including Photonics, Advanced Materials, Nanoelectronics and Microsystems. Power Electronics activities commenced there in 1991 working on the integration of magnetics, initially on substrates and later directly on silicon. In 1999, the team completed an in-depth review of the Status of Power Electronic Packaging for Power Supplies - StatPEP for PSMA. This involved the benchmarking of ten leading edge 100-Watt DC-DC converters covering industrial, military and telecommunications applications areas and identified challenges for the development of the technology in subsequent years. In 2008/2009, Tyndall undertook Phase 2 of “PSiP2PwrSoC” for PSMA – a detailed technology evaluation of leading commercial Power-Supply-in-Package & Power-Supply-on-Chip products.
In 2014 Tyndall delivered to PSMA a state-of-the-art study on 3D power packaging technologies that was highlighted at APEC 2014 (IEEE Applied Power Electronics Conference & Exhibition). The technology and market report included miniaturization and functional integration trends and roadmaps in the movement of power conversion functionality into the load and to embedding of power components into the substrate. The report also summarized an extensive series of interviews with experts from both the power electronics industry and academia to discuss industry and research challenges and directions.
Today Tyndall team research activities relevant to the power electronics industry includes micro power devices, magnetic materials and energy harvesting. Some examples of research activities over the past decade (in collaboration with partners) include:
Since 1988 the Institute has been a designated “Microelectronics Technology Support Laboratory” (MTSL) to the European Space Agency (ESA) and has carried out more than100 technology assessment projects related to Reliability, Workmanship and Assembly Quality, Analysis of Hybrid Circuits and Point of Loads (PoLs), Technology Evaluation of Planar Magnetic and High Density Power Converters.
Tyndall’s power electronics activities are led by Professor Cian Ó Mathúna who has established a research program focused on the convergence of microelectronics and microsystems whereby CMOS provides an intelligent platform for the miniaturization and integration of non-standard functions such as sensors, actuators, power and cooling. This incorporates the development of magnetics on silicon for future power supply on chip (PowerSoC) applications. As a member of the Board of Directors of the PSMA (Power Sources Manufacturers Association), Cian led the first internationally-funded technical review of emerging technology and market trends in power supply on chip (PSiP2PwrSoC). He also led the PSMA funded project (StatPep) previously mentioned and is currently the project coordinator for the EU FP7 project PowerSwipe (Power Supply on Chip with Integrated Passives) -, the first European-funded project on PowerSoc, with partners that include Infineon, Bosch, IPDIA, INSA Lyon and UPM Madrid. In 2008, Cian Ó Mathúna championed the first International Workshop for Power Supply on Chip (www.powersoc.org) which was held in Cork. In 2010, the Second workshop returned to Cork, in 2012 the Third workshop was held in San Francisco and in 2014 the Fourth workshop was held in Boston. It is now considered the flagship workshop for the co-sponsors, IEEE Power Electronics Society and PSMA. In 2013, Cian Ó Mathúna was recognized as an IEEE Fellow with the citation “for leadership in the development of power supply using magnetics on silicon”.

Located in Southern California, PPI’s technical staff continues to lead the way with innovative designs and advances in response to the complex demands presented by the airborne power conversion industry. PPI is owned and operated by its original founders: Jim Haig, CEO and Kris Dill, President.
With engineering and manufacturing housed in one central location, PPI’s dedicated staff works within a team environment that promotes efficiency and allows for the streamlining of product development and on-time deliveries. PPI’s power supplies and modules provide its customers with the highest level of performance, reliability and safety while minimizing the three most sensitive parameters in the industry: size, weight and cost. PPI has developed a loyal customer base of IFEC system and peripheral equipment manufactures as a direct result of superior technical know-how, quality manufacturing and unparalleled customer support. To date PPI has served over 200 customers with a current customer base including:
PFC BOOST CONVERTER MODULES
Providing line rectification, minimized input current harmonic distortion, active inrush current limiting and near unity power factor, PPI’s line of PFC boost converter modules have become an industry standard for hardware design engineers needing an efficient, easily configurable, power supply solution while putting forth minimal design and development effort. When configured with one or more off-the-shelf DC/DC converter modules, avionics’ power supplies with levels exceeding 500W can be easily tailored to meet exacting airborne requirements; including those operating from variable frequency (360-800Hz) generator systems. The PFC boost converter modules are extremely reliable, even in the harshest environments, possessing Mean-Time-Between-Failure (MTBF) rates far in excess of 5 Million hours, validated by 18+ years of statistical field data. AC TO LOW VOLTAGE DC MODULES
PPI began developing a product line of DO160 compliant AC to DC all-in-one modules in 2006 and today the category has expanded to 12 unique modules with a variety of end-use applications. These modules incorporate EMI filtering, active inrush current limiting (as large levels of hold-up capacitances are necessary in airborne applications), a PFC converter than can meet the most stringent requirements for harmonic distortion and near unity power factor from 360-800Hz for new variable speed generator application and a downstream DC/DC forward converter.
PPI has augmented the product offering, increasing output capacity without increasing size and weight and are now able to offer up to 100W of isolated, power factor corrected output power in a 12 cubic inch PCB mountable package.
There are some distinct advantages when incorporating these embedded power supply modules and what they mean for the industry. All equipment used within avionic applications must comply with stringent electrical and environmental requirements, specifically the requirements controlled and governed by RTCA DO-160 and Airbus’ ABD0100. The all-in-one power modules from PPI simplify the process because the modules already comply at the module level and, with just a few external components, are readily adapted to the same specifications at the upper-unit level; this saves time and money and frees up crucial engineering resources to focus on other important system level design tasks.
When the application calls for a discrete supply, typically with more than two outputs or with a 28Vdc input, PPI compliments the modular solution with an array of off-the-shelf discrete power supplies. These airborne compliant supplies available in output levels up to 500W typically power crucial components in the commercial aircraft inflight connectivity system including air-to-ground modems, air-to-satellite modems, high power transponders, antenna control units, ruggedized servers and wireless access points.
