Performance analysis of impedance source converter in different load conditions

Abstract

Nowadays most of the available Power Electronic DC–AC Converters are of buck type voltage source converters. The drawback of these converters is, it is not given equivalent DC source voltage at the output of AC power because of switching and modulation losses. To overcome this problem Impedance Source Converter (ISC) and Battery Energy Impedance Source Converter (BEISC) are used. These converters are voltage source boost and buck type converters and give more and less output AC power when compared to the standard voltage source converters. For modulating the ISC and BEISC, Modified Sinusoidal Pulse Width Modulation (MSPWM) technique is used.
