摘　　要：针对并联型有源电力滤波器的滞环跟踪控制方法的开关损耗较大这一不足进行了改进,将电压空间矢量控制方法与滞环跟踪控制方法相结合,提出了一种电压空间矢量滞环的控制方法。该方法以误差电流为控制对象,在确定误差电流矢量和参考电压矢量区域的基础上,通过一定的控制规则选择最佳的电压输出矢量,并且在误差电流较大时优先采取跟踪速度最快的外环控制策略。该方法加快了电流跟踪速度,有效减少了逆变器的开关次数,降低了开关损耗。最后通过Matlab/Simulink进行了仿真验证。与传统滞环跟踪控制方法相比,该方法具有较大优势。In order to improve the defect of high switching loss of active power filter(APF)hysteresis tracking control method,a control method of APF combining voltage space vector control method with hysteresis tracking control method was proposed.Taking error current as the control object and based on the determination of the error current vector and the reference voltage vector region,the best voltage output vector was selected by certain control rules,and the outer loop control strategy with the fastest tracking speed was preferred when the error current was large.Thereby the current tracking speed was accelerated,the switching frequency of the inverter was effectively reduced,and thus the switching loss was reduced.Finally,simulation verification was conducted by Matlab/Simulink.Compared with the traditional hysteresis tracking control method,it has great advantages.
