The shunt active power filter based on the dSPACE controller can be complemented as a harmonic elimination strategy. The dSPACE controller of APF can realize the sampling of the currents and voltages, detection of compensation current references, high performance fixed-frequency hysterisis current controller and dc-side P1 voltage regulator. The efficiency of control algorithm and parameter testing of APF can be improved and the prototype of APF is built up. The APF to clean the grid current with good compensation performance can be verified by the simulation and experimental results. The feasibility and validity of the APF based on the dSPACE controller are proved.
