Abstract
Multi-input converters (MICs) play a significant role in the aspect of the integration of sources. The reliability of the converter can be enhanced by using a suitable fault tolerance converter design and control algorithm. A dual-input single-output (DISO) DC�DC converter with source fault tolerance is proposed in this paper. In the literature, there are many topologies in this area of work
however, most of them are based on time-sharing control. In this control scheme, one input source is contributed to the load, and others are kept idle in a particular duty interval
hence, this control scheme leads to underutilization of the converter. The proposed converter is designed to circumvent these challenges and can produce boost, buck�boost, and buck operations. And also, it has a source fault feature for achieving the preserved output voltage under source V1 or V2 failure conditions. A 200-W prototype is designed, and the feasibility of the proposed converter is validated through simulation and experimental results. � 2023 John Wiley & Sons Ltd.
