Advances in high breakdown voltage SiC MOSFETs is enabling the use of simpler topologies, such as a half-bridge in medium voltage applications. In order to increase the power output it is necessary to parallel multiple MOSFETs, which can be done in power modules. At high voltage operating conditions parasitic capacitances of the power module become increasingly important to consider, due to increased switching losses and increased risk to cause EMI. A 10 kV, 80 A half-bridge design is presented using four MOSFETs in parallel, with a design focus on minimal parasitic capacitances.
