GaN Systems & USI to Ramp Up GaN Adoption in EVs

GaN power modules enable higher efficiency, increased EV range, and increased EV performance.

GaN Systems has formed a strategic partnership with ASE Technology’s subsidiary, Universal Scientific Industrial Co., Ltd (USI), to co-develop GaN power modules for the EVs.

USIAs the electric vehicle shifts from using legacy silicon power transistors to the increased performance of GaN, power modules are also transitioning to meet the demands of low heat loss and superior voltage control in the power conversion process.

“We are proud to partner with an industry leader like GaN Systems,” said JP Shi, USI’s SVP of Strategic Investment. “We have worked with GaN Systems for years and are impressed with the company’s leadership in high reliability, automotive-qualified GaN – an essential building block for EVs. We look forward to building optimized and highly efficient modules that will be the cornerstone of best-in-class DC-DC converters, on-board chargers, and traction inverters.”

Stephen Coates, GM and VP of Operations at GaN Systems, said, “With today’s announcement, USI joins our ecosystem of partners working to bring leading GaN technology to EVs. Through this partnership, we bring together USI’s leadership in complex, high-power integrated modules with our high-reliability GaN semiconductor technology to build truly disruptive, game-changing modules for next-generation EVs. Building on our deep industry relationships with leaders like BMW, Toyota, and Vitesco, GaN Systems and USI will work together to accelerate GaN adoption across the EV platform.”

GaN power modules enable higher efficiency, increased EV range, and increased EV performance.

The heart of the EV traction drivetrain is the semiconductor power module. USI has more than 20 years of experience in power electronics manufacturing of various package types and high-reliability modules, including power modules, IPMs (intelligent power modules), DC/DC converters, and RF power transistors.

USI has been well-recognized by OEMs and Tier-1 suppliers in the automotive sector by introducing the automotive functional safety standard ISO26262 and being certified with Chapters II and VII for manufacturing.

Power electronics and power conversion have a great influence on the cost and range of an electric vehicle.
