BACKGROUND

Medium voltage (MV) power converters are widely used in MV motor drive applications and in grid connected power electronics systems for integration of renewable energy sources into the power grid. Recent developments in medium voltage wide-bandgap (WBG) semiconductor technology, such as new 10 kV Silicon Carbide (SiC) devices, have enabled simpler topologies for MV converters, making compact and high power density designs achievable. In addition, laminated bus structures with reliable insulation design are crucial for safe operation of MV SiC based power converters.
