Performance Enhancement of Single Phase Voltage Source Inverter used for Solar PV System

Abstract

This paper presents solar PV system based converter topology. Solar PV modules generate dc
voltage at low level and it is required to convert at high voltage level for utilization.
Conversion process consists of two stages dc-dc and dc-ac. harmonic minimization is main
problem associated with the power inverters and reduction of size of the system. In this paper
for minimization of harmonics filter circuit is used and for minimization of size of dc link
capacitor voltage control method for dc-dc boost converter is proposed. Proposed controlling
scheme minimizes system size, cost, harmonics content at the output and increases efficiency
of the conversion system. Simulation results using MATLAB/SIMULINK are also presented.
