摘要 本文介绍了三相PWM整流器的一种基于不定频滞环的空间矢量脉宽调制(sVPWM)电流控制方法。该方法结合了滞环电流控制和SVPWM电流控制的优点,在取得快速电流响应的同时又能有效地降低开关频率,提高系统的运行效率。用Simulink模块库建立仿真模型,仿真结果表明了该控制策略的可行性。 This paper describes a Voltage Space Vector Pulse Width Modulation(SVPWM) control method based on variable-frequency hysteresis current control of 3-phase PWM rectifier.The method combines the advantages of the hysteresis current control and SVPWM current control,during the time of acquiring fasting current response,it debases the switch frequency and enhances the running efficiency of the system.The model of hysteresis SVPWM rectifier is established using simulink blockset and the result proves the feasibility of this controlling strategy.
