According to the requirement of APF's harmonic, the iterative formulas of the Fourier series and the method of prediction were figured out. They can be used to restrain harmonic currents in APF. The system was composed of two single chip microcomputers and some integrated chips. Experiments indicate that its precision and response speed are adapted to the demand of APF.
