Power electronics are playing an increasingly important role in vehicle performance, efficiency and design flexibility as automakers expand their electrified vehicle portfolios. The engagement enables Subaru to explore how advances in power semiconductor integration can support broader system-level optimization, including new approaches to power system architecture, efficiency and vehicle design flexibility, while providing onsemi with practical customer insights to support the continued development of EPP.

“Advancing our electrification strategy requires us to continually assess technologies that can improve vehicle performance, efficiency and system integration,” said Tamotsu Inui, Managing Executive Officer Chief General Manager of Engineering Div, Chief General Manager of Technical Research Center, Subaru. “Our early engagement with onsemi gives us an opportunity to evaluate EPP’s integrated approach to power system design while drawing on onsemi’s modeling, simulation and engineering expertise. We are encouraged by the platform’s potential and look forward to continuing our technical engagement as we develop future electrified-vehicle architectures.”

“The transition to electrification is driving increasingly sophisticated vehicle architectures and placing growing pressure on automakers to improve efficiency, simplify development and accelerate innovation. That is creating an opportunity to rethink power systems from the ground up,” said Dinesh Ramanathan, Senior Vice President of Corporate Strategy, onsemi. “Subaru’s engagement brings valuable customer insight to EPP’s continued evolution, using the platform in advanced customer systems and exploring how its integrated power architecture would support the next generation of electrified vehicles.”

EPP is a breakthrough power platform that enables more power in less space by embedding multiple semiconductor devices directly into a silicon-based wafer-level package.
