GaN solutions enable new V2X charging systems

Infineon Technologies AG has partnered with OMRON Social Solutions Co. Ltd. Combining the company's GaN-based power solutions with the innovative circuit topology and control technology of OMRON now allows one of Japan's smallest and lightest V2X charging systems by OMRON Social Solutions. This partnership will further drive innovation towards wide bandgap materials in power supplies and help to speed up the transition to renewable energies, a smarter grid, and the adoption of EVs while fostering decarbonisation and digitalisation.

For the V2X system, KPEP-A series, Infineon's CoolGaN technology is combined with a unique control technology. OMRON Social Solutions has upgraded its EV charger and discharger system, allowing bi-directional charging and discharging paths between renewable energy sources, the grid, and EV batteries. The series is one of Japan's smallest and lightest multi-V2X systems, with a 60% reduction in size and weight compared to similar conventional charger and discharger designs, yet delivers a charging capability of 6kW. With the integration of the CoolGaN solution, the power efficiency of the V2X systems has grown by more than 10% at light load and around 4% at rated load. By enhancing efficiency and reducing size and weight, the new system enables easier installation and maintenance, allowing more elegant designs and offering a wider range of options for installation locations.

"We are thrilled to partner with OMRON Social Solutions as our CoolGaN based solutions directly contribute to speed up the transition to renewable energies which reduces CO2 emissions and drives decarbonisation," said Adam White, division president of Power and Sensor Systems at Infineon. "It will also make charging of electric vehicles easier and more convenient for consumers, helping to overcome one of the biggest barriers to EV adoption."

Atsushi Sasawaki, managing executive officer and senior general manager for Energy Solutions Business of OMRON Social Solutions, said: "Having access to a broad portfolio of WBG solutions significantly increases the functionality, performance and quality of our products. With Infineon, we get the best-in-class application know-how for creating new and improved charging and discharging systems, providing a high level of satisfaction for our customers and end-users. We look forward to further developing GaN- and SiC-based power solutions together with Infineon to help drive renewable energy and electric vehicles."

Wide bandgap semiconductors made of SiC and gallium nitride differ significantly from conventional semiconductors as they allow for greater power efficiency, smaller size, lighter weight, and lower overall cost. Infineon offers the broadest product and technology portfolio, including silicon, SiC and GaN-based devices.
