Enhanced FPGA-Based Controller for Three Phase Shunt Active Power Filter

A Fuzzy Logic Based Controller for Shunt Power Active Filter

This paper deals with the use of shunt active filter to compensate current perturbations produced by non linear loads. To perform the identification of disturbing currents, the so called Instantaneous Active and Reactive Power Method (pq) is used. A Phase Locked Loop (PLL) circuit, locked to the fundamental frequency of the system voltage, is also introduced for eventual mains voltages perturba...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Modelling of Three-phase Shunt Hybrid Active Power Filter

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 ...

Fuzzy Logic Controller Based Three-phase Shunt Active Filter for Line Harmonics Reduction

Harmonic distortion is a form of electrical noise. It is a superposition of signals, which are of multiples of fundamental frequency. Proliferation of large power electronic systems results in increased harmonic distortion. Harmonic distortion results in reduction of power quality and system stability. This paper presents fuzzy control applicable for active power filter for three-phase systems,...

Three Level Inverter Based Shunt Active Power Filter Using Multi-Level Hysteresis Band Current Controller

In this paper, a three-level inverter based Shunt Active Power Filter (SAPF) using Multi-Level Hysteresis Current Controller (MLHCC) is presented for solution of power quality problems in distribution system. A simulation model of SAPF is prepared in Matlab/Simulink environment. MLHCC is used for control of SAPF currents. In simulation study, it is considered that SAPF executes two tasks coveri...
