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

Abstract

I. IntroductionNetwork simulation has become more important for EMC analysis of conducted disturbances in power electronics over the last years. However, accurate models for the EMI frequency range from 10kHz up to 30MHz are rare and in most cases it is very difficult to obtain the appropriate model parameters. Furthermore, simulation time becomes more and more critical, if EMI phenomena of the whole power electronic system have to be investigated. Therefore, a good compromise between simulation time and model accuracy need to be found. Frequency domain simulations have been established for that task because of its high simulation speed even with complex models. On the other hand nonlinear behaviour of disturbance sources cannot be modeled in frequency domain [3]. Thus, time domain simulation is advantageous for certain simulation problems.Models for induction machines as a part of the EMI noise path have been presented by different authors. Weber has presented an exact model for frequency domain simulation [5] which is a further development of a proposed model by Zhong [6]. This model applies frequency dependent parameters and has high component count which leads to extensive simulation times. Thus, it is not useful for time domain simulations even when dependencies on the frequency are neglected. High frequency models of induction machines for time domain simulations have not been developed up to a comparable accuracy or they are not suitable to simulate both common mode (CM) and

Modeling Induction Motor for Prediction of High frequency problems

“…Most of these models are based on lumped parameter models (Degano et al 2012;Moreira et al 2005;Boglietti et al 2007;Liwei et al 2010;Boglietti and Carpaneto 1999;Moreira et al 2002;Schinkel et al 2006). Distributed parameter based models of induction machine will require many parameters that make extracting those values difficult.…”

“…1a are very difficult to express using analytical formulas (Schinkel et al 2006). Instead, trials and adjustments of R ad and C ad are usually required with the help of frequency-domain simulations to achieve satisfactory results (Schinkel et al 2006).

“…Many investigations have been done on high frequency modeling of induction motor for EMI and over-voltage analysis (Degano et al 2012;Arnedo and Venkatesan 2003;Magdun et al 2009;Weber et al 2004;Boglietti et al 2007;Liwei et al 2010;Boglietti and Carpaneto 1999;Moreira et al 2002;Schinkel et al 2006;Idir et al 2009). Most of them are based on lumped parameter models.…”
