Abstract:
In this paper the thermal management for a traction drive inverter with SiC-MOSFETs will be discussed. The research objective is a high efficiency inverter resulting in a construction space optimized design. A possible approach to achieve these objectives is double-sided liquid cooling for the power modules with high power density. In this paper a three-phase inverter containing three half-bridge SiC power modules will be considered. Several cooling structures and arrangements for the power modules were examined by means of CFD simulation. The performance of the cooling systems is approximately 1 kW with a total power density of the power section of 100 kW per liter.
