Infineon Technologies and OMRON Social Solutions enter into a partnership. Using Infineon's gallium nitride (GaN)-based power supply and OMRON's circuit topology and control technology, a new vehicle-to-everything (V2X) charging system has been developed that is one of the smallest and lightest in Japan.
Wide-bandgap semiconductors made of silicon carbide or gallium nitride differ significantly from conventional semiconductors in that they have higher power efficiency, smaller size and lower weight.
OMRON has further developed the EV charging and discharging system with the new V2X system of the KPEP-A series. Bidirectional charging and discharging between renewable energy sources, the grid and EV batteries is now possible.
Compared to similar conventional charging and discharging systems, the KPEP-A series charging systems are 60% smaller and lighter with a charging capacity of 6 kW.
By integrating Infineon's GaN power supply, the efficiency of the charging systems has been increased by more than 10% at low load and by around 4% at nominal load.
This makes charging electric vehicles easier and more convenient. A planned further development of Infineon's GaN- and SiC-based power supplies is also intended to promote the use of renewable energies for charging electric vehicles.
