This work aims to develop and demonstrate a high density 200-kW three-phase inverter for traction applications with elevated DC bus voltage, e.g., up to 1-kV. A state-of-the-art six-pack 1.7-kV silicon carbide (SiC) power module is used in this design. Custom laminated bussing structure is optimized and detailed design method is presented, achieving ultra-low power loop inductance, along the design of a compact six-channel gate driver board. The inverter is projected to achieve a power density over 55 kW/L. Preliminary experimental testing results are presented in this digest, while additional experimental studies are underway.
