【Abstract】 In this paper,based on the thoroughly analysis about the reason why the original Passive filter didn’t work well, which was used in filtering the quintuple harmonics and septuple harmonics, we introduce two kind of Passive filters design according to raising the power factor and filtering previous harmonics coming from electric-arc furnace. Analysis of simulation result proves that the designing is correct.更多还原
