Abstract

In this paper, a new chaotic PWM inverter is proposed and implemented to reduce the conducted electromagnetic interference (EMI) in induction motor drives for electric vehicles. The key is to design a chaotic frequency modulator to modulate the switching frequency of the space vector PWM inverter. Compared with the sinusoidal PWM and random PWM, the proposed scheme not only suppresses the peaky EMI, but also avoids the occurrence of mechanical resonance. Besides, the proposed chaotic PWM inverter provides good operating performance for the induction motor drive. Both simulation and experimental results are given to support the validity.
