Summary:This paper analyses compensation results and identifies some problems about the PAPF compensation with voltage-source harmonics. Furthermore, it presents a control strategy which is suitable for voltage-source harmonics compensation. Three methods are proposed to detect low-order harmonics in the paper. The lead compensation controller is presented to harmonic current closed-loop control, which can reduce the impact of closed-loop control delay, and improve the FFT results of voltage-source harmonics compensation. Simulation results validate the feasibility of the control strategy proposed in this paper.
