| Abstract | This study introduces a soft-switching non-isolated bidirectional DC–DC converter with high voltage conversion ratio and low voltage stress across semiconductor devices. The presented topology is well suited for high step-up/step-down applications. By integrating coupled inductors and switched capacitors techniques, a high step-up/step-down voltage gain is achieved. Active clamp circuits are employed in both high step-up and high step-down operating states to recycle the leakage inductance energy and realise zero-voltage-switching condition for all switches to mitigate the switching losses and improve efficiency. Also, the reverse recovery problem of the body diodes is completely alleviated owing to zero-current-switching performance. The operation principles and theoretical analysis of proposed converter are presented in details. Finally, the experimental results of a 200 W prototype circuit are provided to confirm the validity of the proposed topology. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
