An Efficient Approach for Predicting Electromagnetic Interference Emission of Motor and Its Driver System Under Field-Circuit and TL Coupling
摘要
Abstract
This paper proposed an efficient approach for predicting electromagnetic interference emission of motor and its drive system under field-circuit and transmission line(TL) coupling.As the common mode interference circuit is the main source of electromagnetic emission,its propagation path is analyzed.On this basis,the key components'models in common mode interference conduction path are established,such as AC induction motor's equivalent circuit modell,drive system's inputs' and outputs'harness model of shielded cable and so on.Then,each part circuit model is connected according to the system's actual combination and the system's EMI prediction model is obtained.Finally,CST MWS and CST CS studio joint simulation method is used to analyze the proposed prediction model and the results are in good agreement with experiment measurement,which validate the accuracy of our proposed approach.关键词
