Germany-based Infineon Technologies has partnered with Visteon-Shinry Power Electronics (VSPE) on a single-stage onboard charger for electric vehicles (EVs).

The unit pairs VSPE’s custom circuit design, control software, and systems engineering with Infineon’s monolithic gallium nitride (GaN) bidirectional power switches.

The single-stage design combines power-conversion functions that conventional two-stage systems manage separately.

It removes the bulk capacitors used in those systems, cutting component numbers, packaging size, system complexity, and manufacturing costs.

Infineon GaN Automotive vice president Benoit Rousseau said: “Together with VSPE we are pushing the boundaries of onboard charging for the next generation of EVs. Our GaN bidirectional switch, recognised 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.”

The charger supports 22kW three-phase AC charging and 19.2kW single-phase AC charging.

It also includes vehicle-to-everything bidirectional capability for vehicle-to-grid power interaction.

Infineon’s monolithic GaN bidirectional switches combine bidirectional voltage blocking and current conduction in one component, reducing the number of semiconductors required.

Their high-frequency switching characteristics enable smaller magnetic components and higher power density.

VSPE is joint venture between US-based Visteon and China's SHINRY Technologies.

Headquartered in Michigan, Visteon operates in 17 countries and develops mobility software, digital cockpits, displays, and EV architecture systems.

SHINRY Technologies, founded in Shenzhen in 2005, produces onboard power solutions, including DC/DC converters and onboard chargers, for new energy vehicles, fuel cell EVs, and digital energy systems.

The company has research and production facilities in Shenzhen, Shanghai, Hefei, and Wuhan.

VSPE co-general manager Zilai Zhao added: “This collaboration brings together complementary strengths in vehicle electronics, power conversion and advanced semiconductors. By combining Visteon’s system expertise and Infineon’s GaN leadership, we’re delivering a transformative solution for next-generation EV platforms.”

Earlier this month, Infineon Technologies and Qualcomm agreed to develop a microcontroller-based subsystem for Qualcomm’s Snapdragon Ride automotive compute platforms.
