| Abstract | A hybrid soft-switching converter including two resonant circuits and an un-regulated dc–dc pulse-width modulation (PWM) circuit is presented. Two split capacitors with four active switches are used at primary side to limit power switches at V in/2. The variable frequency operation is adopted to regulate output voltage. Two flying capacitors are also adopted at the primary side to automatically balance two input split voltages. One un-regulated PWM converter shared the same power switches of two resonant circuits is used to reduce the output current ripple. Therefore, the power rating of power semiconductors and passive components are reduced. The operation principles, performance and effectiveness are illustrated and verified on a 1.44 kW (48 V/30 A) prototype circuit. |

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.
