EPC Space, a joint venture company, will provide advanced, high-reliability, gallium nitride (GaN) power conversion solutions for critical spaceborne and other high reliability environments.

EL SEGUNDO, CA and BLACKSBURG, VA – June 2020 – Efficient Power Conversion (EPC) Corporation and VPT, Inc., A HEICO company (NYSE:HEI.A) (NYSE:HEI)  announce the establishment of EPC Space LLC, a joint venture focused on designing and manufacturing radiation hardened (Rad Hard) GaN-on-silicon transistors and ICs packaged, tested, and qualified for satellite and high-reliability applications.

For over four decades, power management efficiency and cost have improved steadily as innovations in power MOSFET structures, technology, and circuit topologies have kept pace with the growing need for electrical power. In the new millennium, however, the rate of improvement has slowed dramatically as the silicon power MOSFET approaches its theoretical bounds. At the same time, a new material, gallium nitride (GaN) is steadily progressing on its journey toward a theoretical performance boundary that is 6,000 times better than the aging silicon MOSFET and 300 times better than the best GaN products on the market today.

Beyond just performance and cost improvement, the most significant opportunity for GaN technology to impact the power conversion market comes from its intrinsic ability to integrate multiple devices on the same substrate. GaN technology, as opposed to standard silicon IC technology, allows designers to implement monolithic power systems on a single chip in a more straightforward and cost-effective way.

EPC has posted additional modules to the educational video podcast series focusing on reliability and leading-edge applications including high-density computing for Artificial Intelligence (AI), lidar for robots, drones, and cars, and Class-D audio using gallium nitride FETs and ICs.

EL SEGUNDO, Calif. – April 2020 – Efficient Power Conversion (EPC) Corporation has posted an update to its popular “How to GaN” video podcast series. The six videos included in the current release of the series provide practical examples to help designers employ GaN technology to create state-of-the-art DC-DC converters for AI servers and ultra-thin laptops, lidar for robots, drones, and autonomous cars, and audio systems with the highest quality acoustics possible.

Three years ago, the cost of making medium voltage eGaN FETs fell below the cost of equivalently rated power MOSFETs. At that time EPC decided to use the performance and cost advantages of eGaN FETs to aggressively pursue applications with input, or output, voltage around 48 V. Specifically, automotive and computer applications is where 48 V conversion is becoming the new architecture, the new standard for power systems.

EPC’s Phase Eleven Reliability Report adds to the knowledge base published in the first ten reports. With this report, EPC demonstrates field experience of 123 billion device hours and a robustness capability unmatched by silicon power devices.

EL SEGUNDO, Calif.— April 2020 — EPC announces its Phase Eleven Reliability Report, documenting the strategy used to achieve a remarkable field reliability record. This strategy relied upon tests forcing devices to fail under a variety of conditions to create stronger products to serve demanding applications such as lidar for autonomous vehicles, LTE base stations, vehicle headlamps, and satellites to name just a few. 

Based on the third edition textbook, GaN Transistors for Efficient Power Conversion, EPC has posted the first half of a 14-part educational video podcast series on the theory, design basics and applications, such as lidar, DC-DC conversion, and wireless power using gallium nitride FETs and ICs

EL SEGUNDO, Calif. – March 2020 – Efficient Power Conversion (EPC) Corporation has posted an update to its popular “How to GaN” video podcast series, These updated videos are based on the recently published third edition textbook, GaN Transistors for Efficient Power Conversion. This 14-part educational video podcast series is designed to provide power system design engineers a technical foundation and application-focused toolset on how to design more efficient power conversion systems using gallium nitride-based transistors and integrated circuits.

An integrated circuit made using GaN-on-Si substrates has been in production for over five years. The ultimate goal is to achieve a single component IC that merely requires a simple digital input from a microcontroller and produces a power output that drives a load efficiently, reliably under all conditions, in the smallest space possible, and economically. Discrete power transistors, whether silicon-based or GaN-on-Si, are entering their final chapter. Integrated GaN-on-Si can offer higher performance in a smaller footprint with significantly reduced engineering required.

Gallium Nitride (GaN) power devices have been in volume production since March 2010 with remarkable field reliability. This article details how by testing parts to the point of failure an understanding of the amount of margin between the data sheet limits can be developed, but more importantly, an understanding of the intrinsic failure mechanisms can be found. By knowing the intrinsic failure mechanisms, the root cause of failure, and the device’s behavior over time, temperature, electrical or mechanical stress, the safe operating life of a product can be determined over a more general set of operating conditions.
