| Abstract | This study presents the qualitative and quantitative analyses, design procedure and experimental results on a soft switching cell applied to a high-voltage gain interleaved boost converter. An active snubber cell is proposed as a possible solution for the increase of efficiency in a hard switching topology, where switching losses are drastically minimised. The main advantages of the introduced circuit are the common source terminal to all switches; zero-voltage switching of the main switches; zero current switching of the auxiliary switches; low-voltage stress across the switches; balanced voltage across the output capacitors; the presence of a magnetic coupling cell, which allows the gain to be significantly increased; and the magnetic components that are designed for twice the switching frequency. A prototype rated at 500 W is implemented and evaluated, where relevant issues are discussed to validate the theoretical assumptions. |

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.
