【摘要】 本文提出了一种应用于电流控制电压源逆变器的新颖的电流滞环跟踪控制器。此控制器通过在滞环比较器中引入一个一阶内部反馈环节，实现对电流误差的比例加微分控制，以缩小逆变器开关频率变化范围和减少输出电流的纹波。应用于有源滤波器的仿真结果证实，该方法是有效的。更多还原

【Abstract】 This paper presents an novel hysteretic current controller which is used in current-controlled voltage-source-inverter. By adding a inner first-order negative feedback loop,the control1er provides a proportionalplus-derivative control to the current error which results in reduced variance of the switch frequency and reduced ripple of tbe inverter output current. The effectiveness of the controller which is used in the active filter has been proved by the simulation.更多还原
