LBG1K0120G

35kW 1000V Liquid Cooled Bidirectional ACDC Power Module

Product Introduction

LBG1K0120G is the bidirectional ACDC power module used to connect the battery or DC bus to the AC grid. It specifcally aims for bidirectional applications in V2G/VPF function EV chargers, retired battery utilization and the micro grid. It can also replace traditional PCS for energy storage systems. With the high frequency MOSFET/SiC switch technology, it can achieve excellent performance, high power density, high expansion ability and high reliability. By employing liquid cooled design, it features high protection and zero noise.
