Abstract
In this paper
the transfer method from three-phase into single phase is introduced by way of transferring waveform control from three-phase APF into to that of three single-phase so to use mature repetitive and state feedback control strategy. The system stability is improved by the use of the feedback control strategy. The control idea of correction accuracy of output current waveform is improved by the repetitive control strategy and the effectiveness of the method is verified by the simulation.
