| Abstract | This paper studies, explores and analyses a wireless power transfer (WPT) system using current-fed power electronics topology for electric vehicles and battery charging applications. The main contribution is analysis, design, and implementation of a current-fed technology for WPT application. The required resonance in both the transmitter and receiver coils is parallel (L)(C) and series (LC) type, respectively. A detailed mathematical analysis and design have been reported. Stiff DC current at the input of the inverter limits the inverter switch current stress. Also, the inductor in DClink provides natural short-circuit protection during inverter fault. It is quite important in such application. Resonant converter facilitates soft-switching at turn-off of the transmitter side switches. Also, soft-commutation of rectifier diodes reduces reverse recovery loss. Mathematical analysis is verified by simulation results using PSIM 9.3. A 420 W proof-of-concept lab hardware prototype is developed and the experimental results are demonstrated to validate the mathematical analysis and simulation results. The maximum efficiency of DC–DC WPT stage obtained from the proof-of-concept lab-prototype is close to 90% with a coefficient of coupling 18%. It is suitable for solar-to-vehicle and single-phase residential slow charging. |

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.
