Abstract | This paper presents a high-efficiency isolated boost DC-DC converter with low-voltage high-current input based on a new principle of natural commutation. The proposed circuit comprises interleaved full-bridge DC-AC inverters on primary and parallel-connected bridge-rectifiers on the secondary side of a high-frequency isolation transformer. Commutation between inverters is established by the voltage across series capacitors inserted in the output of DC-AC inverters. Zero-current-switching (ZCS) of the load current is realized through commutation using no resonance operations. The operation principle, characteristics and design method are analyzed and presented herein. The feasibility of the proposed DC-DC converter is verified from its high efficiency of greater than 97% over the wide range of 20-100% of the rated load with input conditions of 25 V, 50 A, and approximate output of 350 V, 1.2 kW. |

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.
