Using Datasheet Information to Predict the Power Dissipation of a Hybrid Silicon Carbide IGBT Module in a Voltage Source Inverter

In this paper a method of predicting the power dissipation in a hybrid Silicon Carbide IGBT power module using primarily the information available from the datasheet is shown. Mathematical modeling of the switching device is accomplished using MathCAD for the purpose of power dissipation calculation. The power dissipated is calculated on a pulse-by-pulse basis to allow for any arbitrary waveform to be studied. The mathematical model is validated by way of comparing the results with the power dissipation results calculated by manufacturer's proprietary software.
