Efficient HF Modeling and Model Parameterization of Induction Machines for Time and Frequency Domain Simulations

Abstract

In this paper, a simple but highly accurate high frequency model of induction machines for time and frequency domain simulation is presented. The proposed model enables exact simulation of both, differential and common mode behavior in the EMI-frequency range up to 30MHz. All parameters are easily obtained by differential and common mode impedance measurements and proposed calculation methodology. The model is verified for several induction machines in the power range of 370W up to 45kW. Comparison of simulation and measurement results confirm the good compromise between simulation time and accuracy even in complex simulation problems
