摘要
本文以三相开关磁阻调速电动机（简称SRD）为研究对象，提出了一种三相单三拍固定导通角PWM调压调速控制方案。在线性模式的基础上，对单绕组双开关型主电路的两种PWM电流斩波方式的电流、转矩作了理论分析和计算，并结合样机所获取的性能数据，进行了详细的分析研究，最后得出了斩单管方式SRD的总体性能优于斩双管方式的结论。
According to the characters of three-phase switched reluctance drive (SRD), this paper presents a control scheme of voltage -speed regulating mode by PWM with three phase-single three beat and constant conduction angle. Based on linear model, the paper gives a theorical analysis and caIculation of the current and torque of two kind of PWM chopping current mode for single winding-double switching main circuit, and analyses the characteristic and date frorn a prototype. Finally it draws a conlusion that SRD's whole characteristic of chopping single switching method is superior to chopping double swithching method.
