Experimental investigation of an indirect current controlled Fuzzy-SVPWM based Shunt Hybrid Active Power Filter

Abstract

This paper explores on experimental investigation of Shunt Hybrid Active Power Filter (SHAPF) for mitigation of harmonics and reactive power. In the present work, a Fuzzy Logic Controller (FLC) is implemented for generating desired harmonic reference currents and for regulating the DC side voltage of SHAPF. To efficiently utilize DC side voltage, Space Vector Pulse Width Modulation (SVPWM) is used for generating desired pulses required for Voltage Source Converter (VSC) in shunt Active Power Filter (APF). Experimental analysis has been carried out to assess the proposed control scheme. The control algorithm of the SHAPF is realized in digital domain using Spartan 6 Field-Programmable Gate Array (FPGA) controller. The fundamental necessities for the application structure require careful selection and configuration of elements of SHAPF. The hardware design of components of SHAPF is exhibited in this paper. The outcomes of this paper confirm the viability of SHAPF through 150V/1.5kVA experimental setup.
