Visteon, SHINRY and Infineon Collaborate on Breakthrough Single-Stage Onboard Charger with GaN BDS Technology

­Visteon Corporation and SHINRY Technologies Co. Ltd., through their joint venture Visteon-Shinry Power Electronics LLC (VSPE), are collaborating with Infineon Technologies AG, global market leader in automotive and power semiconductors, to develop a single-stage onboard charger (OBC) for electric vehicles. Designed to deliver high efficiency and reliability while reducing system size, complexity and cost compared to traditional designs, the solution combines VSPE’s advanced converter hardware topology, proprietary control strategy and system integration expertise with Infineon’s gallium nitride (GaN) monolithic bidirectional switches (BDS). The companies announced their collaboration during the electronica trade fair in Munich, Germany.

VSPE’s single-stage architecture combines power conversion functions traditionally handled by separate stages and eliminates the bulk capacitors found in conventional two-stage OBCs. The approach improves reliability, reduces system complexity, enables more compact packaging, and lowers cost. The onboard charger supports both 22 kW three-phase and 19.2 kW single-phase AC charging, with full vehicle-to-everything (V2X) bidirectional capability, enabling grid interaction and greater energy flexibility.

Infineon’s GaN BDS technology is particularly well-suited to the requirements of the single-stage architecture. Unlike conventional power switches, the monolithic devices integrate bidirectional voltage blocking and current conduction into a single device, allowing bidirectional switching functions to be implemented with fewer semiconductor components, simplifying the power stage. GaN’s high-frequency switching capabilities also help increase power density and reduce the size of magnetic components.

“This collaboration brings together complementary strengths in vehicle electronics, power conversion and advanced semiconductors,” said Zilai Zhao, Co-General Manager at Visteon-Shinry Power Electronics, “By combining Visteon’s system expertise and Infineon’s GaN leadership, we’re delivering a transformative solution for next-generation EV platforms.”

"Integrating Infineon's GaN switches with our proprietary single-stage topology is a game-changer for power density and system cost,“ said Mark Sun, SHINRY CTO, “Our R&D team is fully committed to validating this innovative architecture to meet the rigorous reliability standards of global automotive customers."

“Together with Visteon-Shinry Power Electronics we are pushing the boundaries of onboard charging for the next generation of electric vehicles,” said Benoit Rousseau, Vice President, GaN Automotive at Infineon. “Our GaN bidirectional switch, recognized as a ‘Global New Energy Vehicle Innovative Technology’ at the 2026 World New Energy Vehicle Congress, combines leading-edge switching performance and efficiency with a new level of semiconductor integration, enabling new power conversion architectures.”
