This paper discusses the measurement of the input capacitances Cgs and Cgd of SiC and GaN power FETs in order to implement simulation models with an improved mapping of the drain-source voltage vds and drain current id during the switching operation. Based on the gate charge characteristic measured at an inductive load condition using different drain current values and temperature settings, the gate current is allocated to the charging of the gate-drain capacitance Cgd and the gate-source capacitance Cgs. With this approach the capacitance characteristics Cgs(vgs) and Cgd(vgd) are determined in the full operating range of the gate-source voltage vgs and gate-drain voltage vgd.
