Development and Validation of a Multi-Source Bridge DC–DC Converter for EV Applications

Abstract

As per the current scenario of exhausting the oil supplements across the globe because of rapid increase in the consumption of conventional resources which causes the destruction of environment and human life as they emit CO2, SO2 and oxides of nitrogen gas. Hybrid Electric Vehicle (HEV) plays vital role now a days to overcome the above hazards. This article provides a detailed investigation of a multi-input DC converter (MIC) including its mathematical modelling, design, validation of the prototype, and analysis. This converter actively accepts solar photovoltaic (PV) panels and fuel cells as sources. Converter achieve broad control of output voltage and power flow with help of multiple switching frequencies. The steady-state modeling are demonstrated to achieve accurate design and analysis. The recommended converter assurances reduced stress on voltage, fewer switches, and fewer circuit components while offering higher gain and 96.4% efficiency.
