Numerical Field Analysis of Switched Reluctance Motor coupling to Single Phase Diode Bridge Rectifier and Asymmetric Bridge Converter Circuits

摘要

This paper presents a characteristic analysis of switched reluctance motor (SRM) considering DC link capacitor voltage ripple on hard chopping mode by using time-stepped voltage source finite element method in which the time varying magnetic field is coupled with single phase diode bridge rectifier and asymmetric bridge converter circuits. We also examine the influence of freewheeling diodes and DC link voltage ripple on the performance of a SRM such as torque ripples and radial force on the surface of the teeth. The freewheeling diodes and DC link voltage ripples must be taken into account in predicting the performance of the SRM.
