The problem of controlling single-phase shunt active power filter is addressed in presence of nonlinear loads. The control objective is twofold: (i) compensation of harmonic and reactive currents absorbed by the nonlinear load; (ii) regulation of the inverter output capacitor voltage. A two-loop cascade control strategy is developed that includes an inner-loop designed, using the backstepping t...

This paper proposes a novel fuzzy switched controller (FSC) integrated in direct current control (DCC) algorithm for single phase active power filter (SPAPF). The controller under study consists of conventional PI controller, fractional order PI controller (FO-PI) and fuzzy decision maker (FDM) that switches between them using reduced fuzzy logic control. The proposed controller offers short re...

3 (Assistant Professor, Department of electrical engineering, Rajasthan technical University kota, (India) ABSTRACT In recent years, active power filters has been widely studied. A lot of active power filtering methods has been proposed to reduce total harmonic distortion (THD) of source current and to improve the power factor on electrical system. Several advance control strategies are based o...

Abstract. The paper presents a compensating system for the harmonics and the reactive power using active power filter in three-phase and four-wire systems. The conventional active power filters have been designed based on the p-q theory. However, these types of the filter can only compensate for the reactive power for the load and the detection result is not accurate if the three-phase voltage ...

-A three-phase hybrid series power filter is constituted by a series active filter and a passive filter connected in parallel with the load. The control strategy is based on the “dual formulation of the electric power vectorial theory”. The proposed algorithm eliminates the current harmonics of supply. It also improves the power factor and harmonic compensation features of the associated passiv...

The three-phase Shunt hybrid APF topology for harmonic mitigation in low and medium voltage power distribution systems consists of a VSI based three phase shunt active filter (SAF) and tuned passive filters (TPF) connected in parallel with the load. This chapter discusses the modelling of shunt active filter and design of filter interfacing inductor, DC bus capacitor, tuned passive filters. It ...
