New topologies for photovoltaic-fed single-stage boost inverters

Abstract

In photovoltaic-fed applications, boosting the limited output voltage is very essential. Single-stage boost inverters can efficiently be used to interface renewable energy sources. In this paper, different topologies for the boost inverter, namely, (Interleaved, Cascaded, and Hybrid-Cascaded) are proposed with recommended applications for each type. Simulation results elucidate the proposed concepts.
