单周控制有源电力滤波器具有检测量少、控制器结构简单以及鲁棒性强等优点。基于双极调制方式的单周控制三相四线制有源电力滤波器以峰值电流检测的控制方式和纹波电流的存在导致补偿后的电源电流中含有直流分量。文中提出一种基于单极调制方式的新型单周控制三相四线制有源电力滤波器能够有效抑制直流分量的产生,同时降低了开关损耗。仿真结果验证了理论分析的正确性。
One-cycle control of active power filter with less detection, the controller structure is simple and robustness and so on. One-cycle control based on bipolar modulation The three-phase four-wire active power filter has the control method of peak current detection and the existence of ripple current, resulting in the DC component of the compensated power supply current. In this paper, a new type of single-cycle controlled three-phase four-wire active power filter based on unipolar modulation is proposed to effectively suppress the generation of DC components and reduce the switching loss. The simulation results verify the correctness of the theoretical analysis.
