This paper proposes a new drive circuit for reducing the switching current ripples in a switched reluctance motor (SRM). The authors have already presented an instantaneous flat torque control for SRMs, and confirmed its effectiveness through experimental results. However, the switching current ripples also cause torque ripples, and therefore, the current ripples should be decreased to reduce the torque ripples even more. The proposed circuit with parallel capacitor can realize such a reduction. The validity of the proposed drive circuit is verified experimentally. C. 2018Wiley Periodicals, Inc.
