Performance Evaluation of A Positive Output Voltage Dual Input DC-DC Converter

The concept of Multi-Input DC-DC (MIDC) converters have been proposed to conquer the demerits linked with the traditional methods of integration. A Positive Output Voltage Dual Input DC-DC converter (PODIC) that has the capabilities to surpass the demerits of conventional buck-boost converter topology with dual input, that has inverted output voltage is presented in this paper. This converter shall be operated in all the basic modes like buck-boost, boost and buck. A comprehensive explanation of various operating modes, derivation of the expression for the output voltage, and inductor status in all the three basic operating modes have been described in this paper. Also, the feasibility study of the converter is done with the support of simulation and experimental analysis. Efficiency analysis of PODIC is also done in all the modes to highlight the efficiency profile of PODIC.
