Shunt Hybrid Active Power Filter （SHAPF） can improve the performance of passive filter and realize harmonic suppression and reactive-load compensation in large power situation. It covers the shortage of using single passive filter or single active filter harmonic suppression and reactive-toad compensation. The principle and compensation characteristic of Shunt Hybrid Active Power Filter are analyzed by establishing single-phase equivalent circuit of SHAPF in the paper. A design method of main circuit is presented by studying the scheme of main circuit. It includes design of power filter, design of coupling transformer, design of output filter and design of control strategy of active power filter. Simulation model is established based on MATLAB/Simulink, and the parameters ofsimulationmodel are presented. The simulation result indicates the novel Shunt Hybrid Active Power Filter can improve the performance of passive filter or single active filter, the validity of circuit design is proved.
