Abstract

In this paper, an analysis and experimental study of three kinds of inverters are presented. Beginning with the traditional full-bridge buck inverter; followed by two different inverter approaches, the boost and buck boost ones. These last two converters have the property of producing an output voltage higher or lower than the input voltage additionally to its inversion capability, which is a desired characteristic in some applications. The paper include a comparison between the different inverter approaches, additional to the analysis and experimental results of the converters. The control strategy used for all the converters is the sliding mode control in order to introduce a good dynamic response for the closed loop system
