Abstract

A single phase voltage-controlled active power filter(APF) is introduced to improve power quality and to reduce harmonic generated from nolinear loads. Real and reactive power control scheme was addressed using a new power circuit model. By analyzing the reactive power, a unit power factor control scheme was proposed. Simulation and experiment results using a nonlinear diode rectifier showed that the voltage-controlled APF, unlike the current-controlled APF, can reduce the voltage harmonics as well as current harmonics. Also the results showed that the input power factor was greatly improved.
