摘要

本文讨论了基于功率因数校正(PFC)的zeta变换器馈电开关磁阻电机(SRM)驱动作为低功耗应用的成本有效解决方案。通过改变用于4相SRM的中点转换器上出现的直流母线电压来控制SRM的速度。zeta变换器设计为电感电流连续模式，用于调节直流输出电压，提高交流电源的电能质量。当SRM由二极管桥式整流器供电时，交流电源电流的总谐波失真(THD)为70%至80%，根据IEEE- 519电能质量标准，该失真率降至5%以下。

Improved power quality zeta converter fed switch reluctance motor drive

This paper deals with the power factor correction (PFC) based zeta converter-fed switch reluctance motor (SRM) drive as a cost effective solution for low power applications. The speed of SRM is controlled by varying the DC-bus voltage appearing across the midpoint converter used for a 4-phase SRM. The zeta converter is designed in continuous inductor current mode, to regulate the DC output voltage and to improve the power quality of AC mains. Total harmonic distortion (THD) at AC mains current when SRM is fed by diode bridge rectifier is observed 70% to 80% which is brought down to less than 5% as per the IEEE- 519 standard for power quality.
