Abstract

In this paper, a detailed step-by-step modellingapproach is proposed for Silicon Carbide (SiC) MOSFET half-bridge power modules. The drain-to-source current, anti-paralleldiode and parasitic capacitors are accurately modelled consider-ing temperature dependency. A step-by-step parameter extractionmethod based on datasheet is introduced. A SPICE model is builtbased on the proposed modelling approach for a commercialpower module. The model is verified by comparing experimentand PSpice simulation results of the same double pulse tester(DPT), which proves the effectiveness of the modelling approachfor analysing switching losses and converter design. The proposedmodelling approach can help the converter designers quickly andaccurately develop their own models for SiC MOSFET powermodules.
