Abstract

This paper describes a controlling method of motor-terminal surge voltage and induced-electromagnetic interference (EMI) noise which is effective in electric vehicles (EVs) with high density packaging structures. First, high frequency circuit parameters (HFCPs) to influence surges occurring at the motor terminals when a motor is connected to a pulse width modulation (PWM) inverter with short leads are clarified through transient circuit analyses and experiments. Then, a controlling method of the surge voltage and induced-EMI noise is proposed which uses a multi-layer power printed circuit. By applying the clarified HFCPs to an equivalent circuit expressing the multi-layer power printed circuit, damping resistance and bypass capacitance for suppressing surge voltage and the induced-EMI noise are determined. The effectiveness of the surge voltage and EMI noise controller using the values obtained through the analyses is verified through simulations and experiments.
