摘　　要：为了更好地解决传统的电流滞环控制存在的开关频率高和开关损耗大等问题,在传统滞环控制的基础上,提出了一种基于空间电压矢量(SVPWM)的不定频滞环电流控制方法.此方案可以有效降低平均开关频率,减少开关损耗,提高系统的运行效率.通过Matlab/Simulink软件进行了系统仿真分析,结果验证了该控制策略的可行性和有效性.In order to deal with the problems of high switching frequency and switching loss for the method of hysteresis, the method of indefinite frequency hysteresis control based on SVPWM is put forward. The method helps reduce the average switching frequency and switching loss, improves the efficiency of the system. Moreover, through the simulation of the Matlab/Simulink, the results verify the feasibility and effectiveness of the method.
