| Abstract | The input impedance of a wireless power transfer system is heavily influenced by variation of the load impedance, distance between coils and presence of any massive conducting or shielding structures that may exist around the system. To achieve the maximum efficiency for the wireless link transfer one has to ensure good matching between the power source and the wireless power transfer (WPT) system for different working conditions. In this paper an equivalent circuit of the WPT which accounts for the effects of the proximity of massive conducting structures is developed. A novel tapped capacitance impedance transformer for dynamic matching purposes is introduced and its presence incorporated into the equivalent circuit; its effect on the efficiency of the system is investigated. |

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.
