| Abstract | A new zero-voltage switching (ZVS) DC converter with less power switches is presented in this study. The proposed converter includes three subcircuits connected in parallel with the same switches to share load current. Thus, the proposed converter has less switch counts compared with the conventional parallel ZVS DC/DC converter and the output filter inductances and the transformer windings are reduced. Three-level diode clamped converter is used to reduce the voltage stress of switches at V in/2. The input two capacitor voltages are automatically balanced by adding two flying capacitors in three-level DC/DC converter. The current doubler rectifiers are used at the output side to reduce the output current ripple. The output capacitances of metal oxide semiconductor field effect transistors (MOSFETs) and resonant inductances are resonant at the transition interval. Thus, MOSFETs can be turned on under ZVS. Finally, experiments are provided to verify the effectiveness of the proposed 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.

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.
