100kW-Class SiC Inverter Design for Series Hybrid Electric Propulsion System of Military Vehicle

This paper proposes the design process of an inverter for 100kW-class military vehicle applying SiC-MOSFET. The SIC-MOSFET was selected in consideration of the performance and ease of design of the SIC-MOSFET, and the gate driver, DC-link capacitor, and heat sink were designed in consideration of the fast switching characteristics of the SIC-MOSFET and EMI noise. The designed SIC-MOSFET inverter was verified performance of the switching device through Double Pulse Test experiments and the performance of the inverter was verified by dynamo experiments.
