Conducted EMI from motor drive system of electric vehicle under load operation

A complete test for conducted EMI from the direct current fed (DC-fed) alternating current (AC) motor drive system in an electric vehicle (EV) under load conditions is set up to analyze the conducted voltage and current of high voltage DC cables in a frequency range of 150 kHz–108 MHz at 500rpm and 2500rpm with 50Nm load torque of the EV motor with space vector pulse width-modulation (SVPWM) control. The effect of the motor speed increased form 500rpm to 2500rpm on conducted EMI are presented and verified by simulation and experiment. The comparison between the conducted EMI from three bridge legs and that of one bridge leg in the power inverter is presented.
