Switching cell design optimization of SiC-based power modules for current source inverter applications

In this paper, a novel full-SiC power module suitable for three-phase Current Source Inverter (CSI) applications is presented. Based on state-of-the-art CSI modules, the problems associated with layout asymmetry are analyzed through electromagnetic (Finite Element Analysis software) and electrical simulations (Spice environment). Prototypes of the power module layouts are fabricated and parasitic measurements are carried out using a precision impedance analyzer.
