为消除单相整流装置产生的谐波，提出了一种基于二象限有源滤波器（APF）的单相功率因数校正器，包括其主回路拓扑与控制策略。使用T型拓扑可滤除高次谐波，在主回路加装二极管可削减有源滤波器电流峰值，并在控制回路中使用双前馈以实现快速响应。对该拓扑和控制方案进行了Matlab仿真，并设计了基于dsPIC33F系列数字控制器的实验样机。仿真和实验结果均表明该技术可在降低成本的情况下，仍将功率因数提升至99%。

In order to eliminate the harmonics generated by the single-phase rectifier,a single-phase power factor corrector based on two-quadrant active power filter (APF) is proposed. It contains main circuit topology and control strategy. The filter higher harmonics can be eliminated by using T-type topology. The current peak of APF can be reduced by adding a diode in the main circuit. Fast response can be achieved by using double-feedforward in the control loop. The topology and control scheme were simulated in Matlab. An experimental prototype based on a dsPIC33F digital controller was designed. The results from simu-lation and experiments show that the technology can increase the power factor to 99% while the cost is reduced.
