PRODUCTSBidirectional DC-AC conversion module

Space-saving, built-in power conversion module available for V2H system and electricity storage system

A highly efficient power conversion module is equipped with the SiC-MOSFET. An internal non-isolated DCDC converter and single-phase inverter circuit are included, and bidirectional power conversion is possible. This unit can accelerate product development by being incorporated into mass-produced products.

● A power conversion module using the SiC-MOSFET device by Rohm Co., Ltd.

● With a high capacity of 4.5 kW, the size of the device is miniaturized to that of a tissue box (about one-third the size of existing products). Therefore, more space can be secured for other parts (storage battery etc.) at the time of incorporation into products.

● Power conversion efficiency is about 96%
