Recently, SiC power devices are developed to reduce the size and weight of the power converter circuit. This paper presents a three-phase inverter structure for reducing imbalances in the switching loss among power modules connected parallel to one another and among the three phases. A proposed double-sided structure achieved an imbalance of less than 2% in the experimental switching loss using SiC power modules. In addition, it is shown that the double-sided structure realized stable switching behavior under four SiC power modules connected in parallel.
