Research on the Hybrid Active Power Filter
Passive power filter (PF) has problems that source impedance may strongly affect the filtering characteristics and cause system resonance in power system applications. Hybrid active power filter (HAPF) can improve the performance of passive filter and realize harmonics restraint and reactive power compensation in big power situation. In this paper, the principle of HAPF is analyzed, the model of HAPF is established, and the simulation results are discussed.
