Abstract

A transformer less topology for a micro inverter with elevation factor of 1:10 for photovoltaic applications

Abstract:

In this paper, a modified transformer less inverter topology for photovoltaic (PV) applications is presented. This proposal is capable to produce a nine-level AC output from a single low DC voltage source with an efficiency of 95.59%, making it ideal as a micro-inverter. This is achieved by an elevation phase that generates two isolated DC outputs from a single source, using a redesigned DC/DC parallel boost converter that elevates up to ten times the input with no extreme duty cycles and performing it with fewer components compared to similar capacities topologies. These two isolated voltages are employed to feed an asymmetrical cascade cells DC/AC inverter. The theoretical fundaments and both simulation results presented in this paper validate the proposed topology
