Abstract: When fast voltage control is used in a power factor corrector（PFC），ripples on the DC side can cause grid current harmonics. To solve this problem，a novel DC voltage nonlinear PI control strategy was proposed，which could reduce the harmonic content of fast voltage closed-loop in power factor corrector. Base...
