Reduction of EMI by Using Chaotic Sinusoidal PWM on Vector Controlled PMSM

Abstract

In that paper have been studied about using chaotic sinusoidal pulse width modulation (CSPWM) to reduce Electromagnetic Interference (EMI) on vector control driver of permanent magnet synchronous motor (PMSM). KSPWM had gotten, constant switching frequency of SPWM transforms to switching frequency that changes chaoticly in specific interval with helping of chaotic maps. The simulation shows that in PMSM under vector control using CSPWM reduces acustic noise and EMI. In additon to investegate different chaotic maps effect to EMI result of three different chaotic maps have been compared.
