- 675 Sycamore Drive, Suite 150 Milpitas, CA 95035
LBG1K0120G is a bidirectional ACDC power module used to connect the battery or DC bus to AC grid. It is specifically designed for electric vehicle chargers with V2G/VPF function, second-life battery utilization and microgrids. It can also serve as a replacement for traditional PCS in energy storage systems. By adopting high-frequency SiC MOSFET switching technology, it delivers excellent performance, high power density, strong scalability and high reliability. Featuring a liquid-cooled design, it provides a high protection level and enables zero noise operation.
