Baya Reddy Lomada and V. Naga Bhaskar Reddy
Recently, much research has been done on DC converters to enhance the reliability and minimize the overall cost of the converters. This paper presents a detailed study of a multi-input DC–DC converter (MIC), focusing on its mathematical modelling, design methodology, prototype validation, and reliability assessment for low-power applications such as renewable energy systems and electric vehicles. The proposed converter is designed to operate with multiple energy sources, particularly solar and fuel cells. It uses various switching frequencies to achieve extensive control over the flow of power and output voltage. Steady-state modeling and reliability analysis are established to achieve precise design and analysis. This design ensures reduced voltage stress and a simpler circuit with fewer components, improving efficiency and reliability while achieving a higher voltage gain and an efficiency of 96.4%.
