N2 - In this work, an electro-thermal co-design approach is demonstrated to realize a compact 250 kW three-phase three-level T-type traction inverter with a power density of 25 kW/L and 98% peak efficiency. The proposed traction inverter is designed using the best in class silicon carbide (SiC) power modules, novel gate drivers, and most importantly an electro-thermal co-optimization approach. The detailed design process for the laminated busbar, clamped inductive load testing for both phase leg and three-phase prototype, thermal analysis using ANSYS Icepack, novel hybrid cold plate design to reduce specific power, inverter assembly and prototyping are presented in this paper. The proposed prototype has been verified experimentally. The switching performance at rated current and voltage level are presented.
