Summary:
Aiming at EMC (electromagnetic compatibility) problem caused by shaft EMI (electromagnetic interference) noise of electric drive system in EV?ielectric vehicle?j and HEV?ihybrid electric vehicle?j, noise generation mechanism and coupling path are analyzed. Measuring method for shaft EMI noise is proposed and the specific test is conducted. Suppression method of shaft EMI noise are then studied and simple experiments are carried out to demonstrate the effects. The results show that the interference of the shaft noise in electric drive system is so high that poses a serious threat to the operation of the vehicle by the way of conduction and radiation. In order to ensure the electromagnetic compatibility of the electric drive system after integration, the interference suppression measures suitable for loading environment need to be considered.
