Abstract

In this study, an inverter model including non-ideal Insulated Gate Bipolar Transistors (IGBTs) characteristics and a busbar model using impedance measurement is proposed. A motor drive system in Hybrid Electric Vehicle (HEV) consists of a battery, an inverter, a cable, and an electric motor. The inverter is not only a voltage source, but also one of the principal noise sources in the motor drive system. Since switching operations of power devices in the inverter make Electromagnetic Interference (EMI) noise, a non-ideal model of the IGBTs is needed for accurate EMI analysis of the motor drive system. By simulating the motor drive system with proposed non-ideal inverter model, it is possible to predict accurate common mode current noises in view of whole vehicle level. The model is verified by comparison with measurement.
