In order to predict conducted electro magnetic interference (EMI) in inverter-motor drive system, high frequency (HF) motor models are requested and the involved parameters have to be available. In previous studies, the authors have presented an accurate HF model for induction motors and they have defined the procedures to identify the model parameters. In this paper these results are extended to...
Fully digital AC drives with pulse width modulated inverters are becoming an industrial standard. For PWM inverters several strategies are used. A complete view of the most common carrier based strategies, as sinusoidal PWM, third harmonic injected PWM, discontinuous or dead band PWM and space vector PWM is presented. The authors propose a method based on 'quality factors' to evaluate the different...
