基于复合控制的有源滤波器电流控制新方法

为提高有源滤波器的电流跟踪性能，提出一种改进的基于电压空间矢量的双滞环电流控制新方法，该方法利用电流误差矢量与参考电压矢量的空间分布，基于内环的开关状态选择减少高次谐波分量，外环的开关状态选择加快响应速度原则，给出最佳的电压矢量切换，从而有效控制电流误差。电压空间矢量的引入可以提高直流电压利用率，降低开关频率，改善滤波器性能。仿真结果证明了该方法的可行性和有效性。

Novel Current Control Method for Active Power Filter Based on Compound Control

In order to improve the current tracking performance of active power filter,in this paper,a novel double hysteresis current control method based on voltage space vector is proposed.This method chooses the most suitable switching of voltage vector using the space distribution of current error vector and reference voltage vector,based on control strategy which inner hysteresis control should reduce high order harmonic components and outer hysteresis control accelerate current response to control current error...
