Wolfspeed 6.6kW Bi-Directional On-Board Charger

Featured Product from Richardson RFPD


The 6.6kW Bi-directional OBC targets high-efficiency, high-power-density, onboard charger applications. The high voltage rating of Wolfspeed SiC MOSFETs allow the DC bus voltage to vary according to the battery voltage to achieve optimal efficiency.

Wolfspeed SiC MOSFETs in new low-inductance packaging can cut switching losses and simplify designs as seen here. The 6.6kW OBC features C3M0065100K, a 65m?, 1kV MOSFET in TO-247-4L package.

Key SiC System Benefits:
- High efficiency and power density
- Lower circuit complexity
- Bi-directional power flow capability (vehicle-to-grid)

Applications:
- Vehicle battery chargers (V2G)
- Grid-tied distributed generation
- Energy storage
