Unlike silicon, whereby specific manufacturing processes and packaging are required to insulate semiconductors from the effects of radiation, GaN devices are largely resistant to the damage caused by space radiation due to their physical characteristics and structure. In an interview with Alex Lidow, CEO at EPC, Power Electronic News have discovered the features of GaN for space applications.

With the growing adoption of and increasing applications for GaN, Bodo Arlt has taken the opportunity to talk to EPC’s CEO and Co-Founder, Alex Lidow to discuss what he believes is the next big market for this evolving technology
Bodo’s Power Systems
A roundtable discussion with GaN industry experts hosted by Bodo’s Power Systems. Guests included:
- Alex Lidow, CEO and co-founder of Efficient Power Conversion
- Doug Bailey, Vice President Marketing & Applications Engineering at Power Integrations
- Dilder Chowdhury, Director, Strategic Marketing, Power GaN Technology at Nexperia
- Tom Ribarich, Sr. Director Strategic Marketing at Navitas Semiconductor
In this episode, Alex Lidow and Marti McCurdy discusses EPC’s test-to-failure method in improving gallium nitride (GaN) devices. According to Alex, testing to failure has allowed EPC to tease out the exact stressors that cause failure and improve EPC’s GaN devices 10-100 times the reliability of commercial devices, and even 100 times reliability in space applications.
Alex and Marti discuss:
(1:30) Why test to fail
(4:14) Learning from failure data and stressors
(11:38) Safe Operating Area
(14:30) Mechanical stressors
(17:45) EPC Space
Wide bandgap (WBG) semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) are the new frontline in power conversion, and that takes design engineers into a whole new frequency spectrum, as well as power density and form factor opportunities.

The WEAA scheme honors products, companies and individuals that have made outstanding contributions to the innovation and development of the electronics industry worldwide. A committee comprising of ASPENCORE global senior industry analysts and online users from Asia, the US and Europe select the winners. ASPENCORE is the largest electronics industry media and SaaS group in the world featuring media titles including EE Times and EDN.
The ultimate aim of Artificial Intelligence is to provide machines the ability to operate autonomously. One such area which is projected to grow exponentially over the next decade is Autonomous Vehicles. With Artificial Intelligence coupled with the rapid advances in electronics and computer technology, the word driverless will soon take over the roads.

GaN and SiC are becoming much more attractive as prices drop. Several vendors are rolling out the next wave of power semiconductors based on gallium nitride (GaN) and silicon carbide (SiC), setting the stage for a showdown against traditional silicon-based devices in the market.
Alex Lidow has deep roots in the electronics industry. His father and grandfather founded International Rectifier in 1947. Alex eventually ran the company himself for 12 years. He is currently the CEO of EPC, a company that manufactures gallium nitride-based power transistors and integrated circuits. These products are now found in lidar systems for autonomous vehicles, in 4G/LTE base stations, in DC-DC converters for servers and satellites, and in a wide variety of medical products.
EPC proudly announces the induction of Dr. Alex Lidow, CEO and co-founder into the ISPSD Hall of Fame 2019
El Segundo, Calif. – May 2019 – Efficient Power Conversion (EPC) Corporation proudly announces that Dr. Alex Lidow, CEO and co-founder, is inducted into the ISPSD Hall of Fame 2019. This prestigious honor is bestowed upon an honored contributor to advancing power semiconductor technology and sustaining the success of ISPSD. This Hall of Fame award was announced on May 20th, 2019 at 31st IEEE International Symposium on Power Semiconductor Devices and ICs (ISPSD) 2019 at the Marriott Parkview Hotel, Shanghai, China.
EPC's chief executive, Alex Lidow, believes his GaN devices now beat silicon on performance and price, reports Rebecca Pool.
For EPC chief executive, Alex Lidow, this year's PCIM Europe 2019 has been all about applications. Presenting myriad enhanced-mode GaN FETs and ICs in end-products, the company is making a big play for 48 V DC-DC power conversion in advanced computing and automotives.
Efficient Power Conversion, is at the forefront of GaN-based device development. In this video, EPC CEO Alex Lidow talks with Alix Paultre about the various design-ins at the show that underscore the advantages GaN-based devices can provide.

EPC CEO & Co-Founder, Alex Lidow delivers a presentation entitled, Silicon is Dead in the Ridley Engineering booth at APEC 2019.
In this episode of PSDtv Alex Lidow, Chief Executive Officer and Co-Founder of Efficient Power Conversion (EPC) is at APEC 2019 in Anaheim and discusses why their GaN on Silicon devices make Silicon now dead.
New converter topologies and power transistors promise to reduce the size and boost the efficiency of supplies that will run next-generation Artificial Intelligence (AI) platforms. In all the topologies with 48 VIN, the highest efficiency comes with using GaN devices. This is due to their lower capacitance and smaller size. With recent pricing declines in GaN power transistors, the cost comparison with silicon-based converters now strongly favors GaN in all the leading-edge solutions.
Power Electronic Tips
GaN technology has matured to a point where it can challenge traditional silicon technology. Gallium nitride(GaN)-on-silicon low voltage power devices have enabled many new applications since commercial availability began in 2010. New markets, such as light detection and ranging (LiDAR), envelope tracking, and wireless power, emerged due to the superior switching speed of GaN. These new applications have helped develop a strong supply chain, low production costs, and an enviable reliability record. All of this provides adequate incentive for the more conservative design engineers in applications, such as DC/DC converters, AC/DC converters, and automotive to start their evaluation process. In this article, the factors leading to the rapid acceleration of the adoption rate are explored.
In this episode of the PSDcast, we’re talking to Alex Lidow from Efficient Power Conversion about gallium nitride’s (GaN) application in connected automobiles.
