Analysis of a Dual Input DC-DC Converter Topology Based on SEPIC Configuration

Multi input converters are more reliable, efficient and has less complex structure compared to conventional methods of integrating various sources using multiple number of single input DC-DC converters. A dual input DC-DC converter is presented in this paper which can accommodate two different energy sources, two inductors, three power switches. Various modes of operation of the converter are discussed in this paper with the detailed analytical waveforms and equivalent circuits. The software simulation of the presented converter has been carried out using MATLAB/ Simulink® platform for the boost operation of the converter. A hardware prototype of the converter is also developed to check the feasibility of the converter performance in the experimental platform.
