A Simulation Research on Energy Feedback System of Switch Reluctance Motor Based on SVPWM Control

通过结合开关磁阻电动机(简称SRM)的制动工作原理,建立了三相PWM整流器的数学模型和Simulink仿真模型。在此基础上根据开关磁阻电机能量回馈系统的设计要求,将电压电流双闭环控制方式应用于该能量回馈系统中。通过采用空间电压矢量PWM(SVPWM)算法,实现了三相电网电压的空间矢量跟踪。并在MATLAB\Simulink的仿真环境下对系统进行了建模和仿真研究,验证了方案的正确性,为以后产品设计提供了相应的理论依据。

This paper introduces the principle of switched reluctance motor （ SRM ） , establishes the mathematical model and simulation model of three-phase PWM rectifier. According to the design requirements of energy feedback system of SRD, a voltage and current double closed-loop is applied in this feedback system. Through the use of the space voltage vector PWM （ SVPWM ） algorithm, the threephase grid voltage space vector tracking is achieved. The proposed scheme is verified through modeling and simulation research in Matlab/Simulink system, which provides the theoretical basis for the design of the future product.
