Abstract
- This paper proposes and implements a new hybrid chaotic (HC) pulse width modulation (PWM) scheme for the reduction of electromagnetic interference (EMI) in alternating current (AC) motor drives. This scheme utilizes logistic mapping to simultaneously chaoize both the carrier frequency and the pulse position. Compared with available chaotic PWM schemes such as the chaotic-pulse-position-modulated (CPPM) PWM and the chaotic-amplitude-frequency-modulated (CAFM) PWM, the proposed scheme is a synergy of CPPM-PWM and CAFM-PWM. Thus, it possesses a hybrid characteristic, namely the peaky EMI is suppressed while the occurrence of low-order noises is reduced. Both simulation and experimental results are provided to support the validity. [ABSTRACT FROM AUTHOR]
