摘要: In this paper, the implementation of a three-phase shunt active power filter is presented. The essentially three independent single-phase current-controlled voltage source inverters (CC-VSI) with common DC bus. CC- VSI operated to directly control AC grid current be sinusoidal and in phase voltage. APF consists loop, which uses polarized ramptime employs simple Proportional Integral control. experimental results indicate that able handle predominantly harmonics, as well unbalance reactive power, so currents are sinusoidal, voltages symmetrical.
