Category Analysis, Design and Implementation of a High Efficiency Multilevel Converter for Renewable Energy Systems

Abstract

Stand-alone renewable energy systems are used to supply electricity to remote areas where access to the utility grid is not available. Mostly common systems store energy in battery banks in order to compensate intermittence and peak power limitation of renewable energy sources. Because common appliances are designed to operate with the utility, a device capable to convert the DC voltage of batteries into standard AC voltage is necessary. This device is called inverter, and this work presents the analysis, design and implementation of an inverter based on a multilevel topology.

Multilevel inverters are mainly used in high power applications, where they have proved to be reliable and robust. They operate with low frequency and present high efficiency...
