Design of a single-phase inverter controlled by a digital PWM for the optimization of photovoltaic energy

Abstract

The study conducted in this article aims to set up a system for the proper control of power production from a photovoltaic source. The system consists of a PV panel, two DC/DC converters, one controlled by a PWM which ensures the extraction of the maximum power from the panel (MPPT), the second converter will regulate the voltage across the output load. After the DC/DC adaptation stage, a conversion from direct current to alternating current takes place using a single-phased inverter which will be controlled by a unipolar digital PWM to ensure the correct switching of the four transistors.
