In this paper, a neural network based reference current computation method for active power filter (APF) control under non-ideal mains voltage with different load condition is proposed. The neural network controller has been designed to extract fundamental frequency components from non-sinusoidal and unbalanced currents. These fundamental frequency components will be used as unit templates. The APF...
In this paper, a novel neural network based phase locked loop (PLL) less reference current computation method for active power filter (APF) control under non-ideal mains voltage conditions with different load condition is proposed. The neural network controller comprises two similar adaptive linear neurons (ADALINE), and it has been designed to extract fundamental frequency components from non-sinusoidal...
This paper deals with a novel configuration of single-phase hybrid active power filter. One of the advantages of the proposed hybrid filter is its adjustable capability to determine voltage rating and current rating of active power stage by selecting appropriate values for its passive filter parameters. Equivalent circuit of proposed hybrid filter has been presented and its filtering characteristic...
In this paper a novel hysteresis voltage control for a series active power filter is proposed to improve the Power Quality (PQ), which is one of the most important issues of modern electrical distribution. The active filter controller is based on a new control strategy related to hysteresis band voltage control method, where the band is modulated with the system parameters to maintain the modulation...
