Induction motor modeling for common mode and differential mode emission evaluation

The paper deals with the development of a detailed model of a three-phase induction motor useful for evaluating separately common mode and differential mode currents. The proposed approach simplifies the decoupling of the common mode and differential mode current spectra, using the dq0 stationary reference frame transformation, and allowing a separate analysis of the phenomena, which is useful for EMI filter design. The proposed model can also be used to evaluate new inverter modulation techniques in terms of current harmonic generation.
