Product Introduction
LBG1K0120G is the bidirectional ACDC power module used to connect the battery or DC bus to the AC grid. It specifically 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.
