摘要：

Two new pulse width modulation (PWM) schemes: chaos-based sinusoidal PWM (SPWM) and chaos-based space vector PWM (SVPWM) are brought forward. There are cluster harmonics around the multiples of switching frequency in conventional SPWM and SVPWM output waves owing to their fixed switching frequencies. Chaos-based PWM strategies utilize a chaotic changing switching frequency to spread the harmonics continuously to a wideband area so that the peak harmonics can be reduced greatly. This can be an effective way to suppress harmonic and reduce ripple current and torque in induction motor drives. The good agreement between theory and simulation has approved the validity of this study.
