Abstract： There is a certain coupling relationship among the main circuit parameters of a single-phase shunt active power filter (SAPF), which has a great influence on the reasonable selection of various parameter values. By analyzing the calculation methods of the inductance of alternating current (AC) side and the voltage and capacitance values of direct current (DC) side in the existing single/three-phase SAPF main circuit, a specific single-phase SAPF circuit parameter analytical expression was obtained. Aiming at the coupling relationship among the variables in the resulting expression, the model was optimized and analyzed in MATLAB, and a complete set of parameters design scheme was obtained, which ensure the comprehensive optimization target of the post-harmonic content below 2% is compensated under a specific load. The simulation and experimental procedures verify the correctness of the selected parameters.
