Modeling of ZSI based BLDCM For Reduction of Commutation Torque Ripple

Abstract

This paper proposes a new technology, which reduces ripple context in Brush less DC Motor. This technology is having the similar modulation modes in conduction period and commutation period. In Grid applications, Brush less DC motor produces a torque ripple, hence for the reduction of ripple content, a ZSI based BLDCM is proposed in this technology. The buck-boost property of a  ZSI gives a effective reduction of the ripple content and also improves the DC voltage utilization. The MATLAB/Simulink/Simpower system were selected to design and implement a ZSI based BLDCM for less torque ripple content.
