Experimental analysis of conventional buck and boost converter with integrated dual output converter

In recent days, dc-dc power converters are gaining more attention in the power electronic research field. To meet the various level of voltage demand, single input and multiple output topologies (SIMO) are developed. Many such converter topologies are available under this category. Integrated Dual Output Converter (IDOC) is one of the single input multi output topologies. IDOC is a DC-DC power converter which performs both buck and boost operations at the same time with a single power supply. IDOC is derived from the conventional boost converter using couple of power switches. With the shoot through phenomenon both the switches in the IDOC can be connected in series and operated to obtain the boost and buck voltage simultaneously. In this paper, the basic operation of IDOC is presented and compared with conventional buck and boost converter. The hardware prototype model of IDOC with 100W is developed and tested. Also the experimental results are compared and verified with the simulation results. Also the performance comparison among buck, boost and IDOC converter is done and presented.
