| Abstract | The coupled inductor (CI) bidirectional DC–DC (BDC) converters are becoming popular in energy storage applications owing to high range factor, reduced device stress and high efficient. However, the applications of CI-BDC are limited due to the leakage energy of CI. Hence, this work proposes a voltage-clamp (VC) CI-BDC converter that effectively recovers the leakage energy while clamping switch turn-off voltage spikes, thus, guard the device from high-voltage stress. The working principle of proposed BDC converter with its characteristic waveforms and the steady-state analysis is presented. The equivalent circuits are obtained for the each interval operation of CI-BDC converter with voltage clamp in both boost (discharging) and buck (charging) mode. A Simulink/MATLAB-based design is presented for the CI-BDC converter with voltage clamp. A 60 W, prototype of proposed converter has been developed and validated experimentally with the simulation counterparts. To confirm the elimination of leakage energy of CI, the analyses of VC-CI-BDC converter are compared with CI-BDC converter counterparts. |

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.
