Abstract

This paper presents an impedance shaping technique to reshape the common mode (CM) impedance profile of three phase common mode choke. The CM impedance offered by a designed CM choke with specific core area and number of turns is reshaped using CMIS choke. CM noise in a two level voltage source inverter (TL-VSI) has dominant frequency components near inverter switching frequency ( Fsw ). Attenuation of these dominant frequency components demand high impedance at Fsw . A designed CMIS choke offers high CM impedance for Fsw compared to CCM choke. The proposed three phase CMIS choke is a passive CM noise attenuation technique that attenuates the dominant Fsw components. The CM attenuation performance of passive EMI filter with CMIS choke and CCM choke are compared for TL-VSI.
