摘　　要：为剖析PFC技术抑制谐波功率因数的性能,提高间接电流控制策略水平,基于有源滤波器的间接电流控制结构,以单个全桥逆变器作为研究结构,根据最优间接电流控制策略方案对主电路的容量、线路感抗、直流侧电容以及交流侧电感进行参数设计,并在MATLAB中进行非线性负载、感性负载以及容性负载下满载、半载和轻载状态下的补偿性能仿真。结果表明,间接电流控制策略在各种负载时都能补偿谐波,并且能够起到UPS功能的作用。In order to analyze the performance of PFC technology in suppressing harmonic power factor and improve the level of indirect current control strategy,three schemes under indirect current control strategy are analyzed based on three topologies of active power filter.With a single full bridge inverter as the research structure,the capacity,line inductance,DC side capacitance and AC side inductance of the main circuit are designed according to the optimal indirect current control strategy,and the compensation performance under full load,half load and light load conditions of nonlinear load,inductive load and capacitive load is simulated in MATLAB.The results show that the indirect current control strategy can compensate harmonics well under various loads,and can play a role in UPS function.
