摘　　要：电力电子装置的大量应用,造成了工业供电电网侧谐波污染,目前采用有源滤波器进行谐波优化,但控制方法在开关频率和控制精度上存在缺陷。提出了一种基于空间矢量调制和电流定频滞环相结合的有源滤波器控制方法。以一组定频可控环宽的滞环比较器对误差电流进行控制,再结合空间矢量调制的基本思想,实现网侧电流的跟踪控制。特点是稳定了逆变器的开关频率,降低了有源滤波器的总谐波畸变率。在Matlab/simulink环境下搭建仿真,与电压空间矢量法进行比较,仿真结果验证了上述方法的可行性。With the application of power electronic devices, the grid side is polluted by harmonic in industrial power. At present, the control method of active power filters has the defects on switching frequency and control preci- sion. The control method of active power filter base on space voltage vector and the fixed frequency hysteresis current is presented in the paper. Hysteresis comparator with a set of fixed frequency controllable hysteresis width was used to control the error current, and the voltage space vector was combined to realize the fast tracking control of grid cur- rent. The characteristics of this method are to stabilize the inverter switching frequency and reduce tile total harmonic distortion rate of active power filter. Based on Matlab/simulink environment, simulation was carried out and the re- sult was compared with that of SVPWM method, which verifies the feasibility of the method.
