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...

Abstract: Due to the high cable ratio of city grid，the harmonic pollution is aggravated. For the buses with high harmonic voltage content，it is necessary to evaluate the harmonic emission level of the utility side and customer side. Most of the existing evaluation methods are based on two assumptions：1）the harmonic ...
