This final report is on the design and experimental verification of a 200 kVA traction inverter using three 900 V, 2.5 mΩ, SiC MOSFET-based half-bridge power modules comprising the power stage. Each dual power module contains four 900 V, 10 mΩ SiC MOSFETs per switch position and uses synchronous conduction to achieve high average and peak efficiencies over its entire operating region to meet the demands of hybrid, plug-in hybrid, and extended-range electrified vehicle architectures. Significant performance improvement, via conduction, switching, and reverse-recovery loss metrics, from this SiC MOSFET-based inverter—especially at light load conditions—will be discussed.
