摘要

开关磁阻电动机具有结构简单、转子惯量小、单位体积功率大等优点。然而，由于脉冲型间断励磁，SRM存在电流谐波大、功率因数低的缺点。本文研究了一种降低谐波和提高功率因数的SRM驱动系统。该系统由带功率因数校正(SPC-PFC)的开关功率变换器、DC/DC功率变换器和三相逆变器组成。SPC-PFC设计用于产生纯正弦输入电流，提高功率因数并减少谐波。通过仿真和实验验证了系统的性能。

SRM drive system with improved power factor

The switched reluctance motor (SRM) has the advantages of simple structure, low rotor inertia and high power rate per unit volume. However, the SRM has the disadvantages of high current harmonics and low power factor because of the pulse-type discontinuous excitation. This paper investigates an SRM drive system with reduced harmonics and improved power factor. The system consists of a switching power converter with power factor correction (SPC-PFC), a DC/DC power converter and a three-phase inverter. The SPC-PFC is designed to produce a pure sinusoidal input current, improve the power factor and reduce harmonics. The performances in the proposed system are verified through both simulation and experiments.
