Vincotech, a supplier of module-based solutions for power electronics, has launched the first standard power modules featuring exceedingly fast Normally Off SiC JFETs from SemiSouth for high-performance solar inverters. The company implemented the MNPC topology with split outs to achieve remarkable efficiency.

Vincotech has introduced the world’s first power modules equipped with Normally Off SiC JFETs from SemiSouth. Engineered for highly efficient solar inverters, these new products feature a 1200V dual booster input stage and a 1200V MNPC inverter stage housed in a flow0 package with just 12mm assembly height. The modules support highly efficient, three-phase solar inverters ranging up to 30kW. They also feature with exceedingly fast-switching Normally Off SiC JFETs without tail current. The on-board, high-frequency DC link capacitors enhance fast-switching, low-inductive designs and help minimize voltage overshoots. The MNPC topology has been implemented with split outputs to achieve utmost efficiency and high cross-through conduction immunity.
