摘要

This article proposes and investigates a control technique for vibration and acoustic noise reduction in Switched Reluctance Machines (SRMs). A large vibration generally occurs at the turn-off stage of SRM phase voltage due to a sudden decrease in the attraction force. The proposed technique is a smooth voltage Pulse-Width Modulation (PWM) method that utilizes the PWM technique to reduce the rate ...
