A New Computer-Aided Calibration Technique of Physics Based IGBT & Power-Diode Compact Models with Verilog-A Implementation

Abstract

In this work, we present a new calibration technique of an IGBT and power diode compact model using a commercially available tool optiSLang™ [1]. We show that with such a computer-aided technique, we can get a accurate match in switching transients just by calibrating the static (transfer and output characteristics) and the gate charge curves. Furthermore, we present a Verilog-A implementation of a physics based IGBT and power diode compact model [2], [3]. We demonstrate the benefits of a Verilog-A model by comparing the run time and convergence performance with a standard SPICE implementation.
