| Abstract | In this study, the analysis and design of a coupled-inductor (CL)-based ultra-high step-up single-switch DC–DC converter are presented. With the aid of the CL and voltage multiplier cell, the suggested topology can obtain ultra-high-voltage gain without a large turn ratio and extreme duty cycle. A passive clamp circuit is utilised in the structure of the introduced converter for not only alleviating voltage spike on the main switch effectively but also recycle the leakage inductance energy. So low-voltage rating and low on-state resistance metal oxide semiconductor field-effect transistor is allowed to increase efficiency and lower the conduction losses. The input current ripple of the suggested topology is very low due to connecting an inductor to the suggested structure input section, which is very friendly and desirable to the photovoltaic and fuel cell applications. The suggested converter steady-state analysis, operation principle, theoretical efficiency analysis, and design procedure are described comprehensively in this study. Furthermore, the suggested converter superiority is illustrated over various alike recently introduced the most important DC–DC structures in the comparison study. Finally, a laboratory prototype is fabricated with a 225 W output power to confirm the theoretical analysis of the introduced converter. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
