| Abstract | In applications of modern power distribution with distributed energy resources, grid-tied energy storage systems (ESS) will be increasingly incorporated. Energy storage devices (ESD) such as lithium-ion battery or super-capacitor cells however have low DC terminal voltages. It is essential to develop a bidirectional DC/AC converter to interface ESS based on low voltage cells to the higher voltage grid without using high number of cells in series. In this paper a bidirectional current-fed converter with high frequency transformer isolation is proposed. In this proposed topology, a current source inverter (CSI) is used to interface to the grid. A DC/DC converter with High frequency(HF) transformer is used to feed the current to CSI. Low voltage and high voltage side of DC/DC converter can be either Push-Pull or Full-Bridge. The proposed topology has the advantage of reduced component count and simple control strategy. Simulation and hardware results have shown that the proposed circuit can work in charging and discharging of the ESS and the control strategy is effective. |

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.
