Simulation and experimentation of a single stage boost inverter

Abstract

This paper presents simulation and experimental verification of a single stage DC to AC boost inverter for solar photovoltaic (SPV) applications. This topology integrates the boost converter inside the conventional h-bridge inverter topology. This eliminates the need for a separate boost converter. The whole system requires four basic switches of an h-bridge inverter for both boost and DC-AC conversion operation. Overall, the efficiency is improved because no additional switch is required for the boosting operation. The duty cycle variations are implemented using sinusoidal pulse width modulation (SPWM). The firing pulses for switches used in the h-bridge inverter are provided using Arduino-Uno platform. The principle of operation along with the simulation and experimental results are also presented.
