Abstract

For the purpose of electromagnetic compatibility (EMC) performance investigation and prediction, accurate modeling and analysis are performed on IGBT PWM inverters. In this paper, parasitic components and their measurement methods are addressed. Modeling and characterization of parasitic inductance and capacitance within device modules, in inverter assemblies, and inside motor or inductor load are carried out. IGBT device modeling and parameter extraction issues are discussed. A physics-based IGBT model is chosen for the simulation study, which is necessary to obtain correct switching waveforms with high-frequency effects such as dv/dt and current tailing. Experiments have been conducted on hard switching and zero-voltage-transition (ZVT) soft-switching prototype inverters.
