| Abstract | In this study, a new high step-up current-fed zero voltage switching (ZVS) dual half-bridge DC–DC converter is proposed. The presented topology is composed of two paralleled boost half-bridge converters. In this converter, only two switches are efficiently utilised such that the adopted scheme has a simpler control circuit, lower losses and lower cost. It is very noteworthy that over the whole range of load and input voltage variations, the switches keep ZVS operation and the output diodes operate in zero current switching (ZCS) condition leading to high overall efficiency. Also, taking the advantage of voltage-doubler circuits, transformers with lower turn-ratio and diodes with lower reverse voltage can be used to build the desired high output voltage. Regarding the mentioned characteristics, the proposed converter can be well nominated for distributed generation systems. In-depth analysis, design and performance comparison of this new converter are illustrated; then for verification purpose, experimental results with an output voltage of 400 V and output current of 2.5 A are presented. |

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.
