Abstract
This paper presents single-phase SRM drive system with single-stage high power factor and low torque ripple. Single-phase SRM has simple mechanical and electrical structure, robust and high speed operation characteristic. But conventional SRM drive with diode bridge rectifier and filter capacitor has a low power factor because of short charge time of capacitor. Therefore, this paper presents a novel single-phase SRM drive with single-stage structure circuit, which can improve the power factor and reduce peak torque ripple. A novel switching topology is presented base on mathematical analysis. The novel drive method is verified by simulations and experiments.
