摘要

本文介绍了一种低功率(750w)开关磁阻式家用电器电机驱动器，具有接近统一功率因数和低成本的特点。该驱动器的主要特点是简单的速度控制，最小开关数逆变器拓扑，以及基于准谐振升压拓扑的紧凑高质量整流器(HQR)输入级。所获得的结构适合于集成，并允许开发实现所提议驱动器所需的所有主要功能的廉价芯片。本文首先指出了近年来对家电线路电流污染的限制。然后提出了该驱动器，重点介绍了高质量整流器输入级的设计。最后给出了样机的实验结果，以评估所提出的驱动器的效率。

A switched reluctance motor drive operating at unity power factor

The present paper describes a low power (750 W) switched reluctance motor drive for home appliances featuring close to unity power factor and low cost. The key features of the proposed drive are a simple speed control, minimum switch number inverter topology, and a compact high quality rectifier (HQR) input stage based on a quasi-resonant boost topology. The obtained structure is suitable for integration and allows to develop an inexpensive chip implementing all the main functions required by the proposed drive. The paper starts by pointing out recently introduced constraints on line current pollution of home appliances. The proposed drive is then presented emphasizing the design of the high quality rectifier input stage. Experimental results on a prototype are finally presented to evaluate the efficiency of the proposed drive.
