摘要
针对目前电流滞环控制存在的缺点,提出了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,这类控制方案将滞环控制与SVPWM控制有机地结合起来,在取得快速电流响应的同时,降低了开关频率,提高了系统运行效率.本文介绍了基于不定频滞环的SVPWM电流控制原理,并用Simulink模块库建立了仿真模型,仿真结果表明了该控制策略的可行性.
Aming at present disadvantages of current hysteresis controlling, a method of Space Vector Pulse Width Modulation （SVPWM） current controlling based on indeterminate frequency hysteresis is introduced. This controlling project combines the hysteresis controlling with SVPWM controlling. During the time of acquiring fasting current response, it debases the switch frequency and enhances the running efficiency of the system. This paper introduces the theory of SVPWM current controlling based on indeterminate frequency hysteresis and a model of hysteresis SVPWM rectifier is established using simulink blockset . The resuh proves the feasibility of this controlling strategy.
