Current Controlled Grid-Interfaced Photovoltaic Boost Inverter with Particle Swarm Optimisation based MPPT Algorithm

Abstract

This work aims to mitigate the anomalies associated with the transient behaviors of PV cells. A two-stage Boost Inverter comprising of a Boost Converter interfaced with a three-phase inverter is utilized. The switching pulses of the Power Electronic Devices are generated by using an optimised MPPT algorithm to regulate the duty ratio as well as the Reference Current used to generate 6 Pulse PWM signals for the Inverter, which is controlled in the ”DQ” frame using Park and Inverse Park Transformations of the three-phase current obtained after AC conversion by inverter.
