摘　　要：分析了有源滤波器的工作原理,推导了三相三线制有源滤波器单周期控制的数学模型;将数字单周期控制与ip-iq谐波电流检测法相结合,实现了对有源滤波器的控制。与传统单周期控制方法相比较,该方法保留了实时性好、鲁棒性好等优点,又取消了积分器,降低了单周期控制电路的复杂性。使用Matlab/Simulink软件对该方法进行了仿真,并在以DSP为核心的试验平台上进行了验证,仿真和试验结果都证明了该方法的可行性与有效性。The paper analyzed working principle of active power filter, derived mathematical model of single-cycle control of three-phase three-wire active power filter. It combined digital single-cycle control and ip-iq harmonic current detection method to realize control of active power filter. Compared with traditional single-cycle control method, the proposed method retains advantages of good real-time performance and robustness, meanwhile cancels the integrator, and reduces complexity of the single-cycle control circuit. The proposed method was simulated using Matlab/Simulink software and validated by experiment platform with DSP as the core, and the results of simulation and experiment prove feasibility and effectiveness of the method.
