This paper presents a comparison among proportional-integral, variable structure voltage controller and energy balance controller for the control of single phase active filter. Proportional-integral (PI) and variable ...

The paper presents an active power filter (APF) to eliminate harmonics and to compensate reactive power and neutral current of three-phase four-wire symmetrical and unbalanced nonlinear loads. A set of three single-phase ...

This paper presents the analysis of four leg voltage source inverter (VSI) used as an active filter (AF) for reactive power compensation, load balancing, harmonic elimination and neutral current compensation in three-phase ...

In this paper, a 3-phase active power filter (APF) is presented to eliminate harmonics and to compensate the reactive power of an uncontrolled rectifier with capacitive loading taken as nonlinear load. An APF is realized ...
