Abstract | A current fed resonant converter is presented and developed to have the advantages of wide input voltage operation range and less ripple current. The developed circuit includes two boost inverters in the front stage and one resonant converter in the rear stage. Two boost converters are operated using interleave pulse-width modulation in order to reduce the input ripple current. The resonant converter with voltage doubler circuit topology is adopted to obtain high-voltage output and realise zero-voltage turn-on switching for all power switches over all load ranges. The active switches of two boost converters and the resonant converter share the same power switches so that the switch counts in the studied circuit are reduced. In order to extend the input voltage operation range, an additional boost converter is active when the input voltage is lower than the defined voltage level. Therefore, a wide input voltage range operation, 24–76 V, of the developed circuit can be realised to apply in the fuel cells or solar cells input applications. The feasibility and practicality of the developed circuit are confirmed by the test results with an 800 W 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.
