Simulation of Shunt Active Power Filter Controlled by SVPWM Connected to a Photovoltaic Generator

Abstract

Abstract-In this paper we study the shunt active power filter. This filter contains a voltage three-level inverter controlled by the SVPWM strategy supplied by a the DC bus powered by a solar array to improve the quality of electric energy and eliminate harmonics currents generated by non-linear loads, the latter identified by the method of multivariable filter. The objective of this study is to obtain an unpolluted source into the power grid where all the simulation results are obtained by using MATLAB Environment.

Real-Time Implementation of an Open-Circuit Dc-Bus Capacitor Fault Diagnosis Method for a Three-Level NPC Rectifier

“…They have many attractive advantages as compared with two-level converters such as reduced dV/dt, lower voltage stress across power semiconductors, better quality of the output voltages, reduced filter size, etc. [2,3]. Among several power conversion structures, the three-phase three-level Neutral Point Clamped (NPC) is widely preferred since it needs only one dc source and the minimum number of dc-bus electrolytic capacitors.…”
