An Active Power Filter Implemented With Stability Analysis of Voltage Source Inverter Using a Predictive Control Scheme

Abstract

The main aim of project is to reduce the power quality problems in distribution system by using active filter. In this project PV Connected active type power filter is implemented. An active power filter consists of dc link capacitor, grid interfacing voltage source inverter, and filter. The dc voltage is supplied by photovoltaic system which is stored in capacitor. In this project we are using four leg voltage source inverter which converts DC to AC voltage. And the harmonics are eliminated by filter. Predictive controlling scheme use to operate or control the switches of voltage source inverter.All of these functions may be accomplished either individually or simultaneously. And we observed the simulation results by using MATLAB/SIMULINK
