V2G and V2X bidirectional charging
Vehicle-to-grid (V2G) and vehicle-to-everything (V2X) charging lets an electric vehicle send energy back to the grid, a building or another load. The charger must convert power in both directions with high efficiency, grid-quality current and safe control. Semtronics designs bidirectional charging power electronics, both wired and wireless.
Our V2X work
- 11 kW / 22 kW three-phase bidirectional V2X on-board charger for 400 V and 800 V batteries
- 11 kW wireless power transfer V2X prototype to SAE J2954, with a 22 kW system in development
- On-board and off-board V2G chargers for passenger and commercial vehicles
Design capability
- Bidirectional three-phase PFC / active rectifier stages
- Bidirectional isolated DC-DC stages (dual active bridge, CLLC)
- Grid-tie control, low THD and protection
- SiC devices for high efficiency and power density
- Embedded control and vehicle communication
