| Abstract | The efficiency of wireless power transmission via electromagnetic induction is strongly dependent on the distance and the lateral misalignment between the sending and the receiving coils. In this study, the authors propose to adopt a multiple-input–single-output (MISO) coil system to increase the efficiency of energy transmission in case of large air gap misalignment between coils. The sending part consists of a matrix of air-core coils, in which only the four coils under the receiving coil, supplied with the same current, contribute to energy transmission. To orientate the magnetic field and to reduce the energy losses, they propose to power the two nearest neighbour coils with low, out-of-phase, excitation current. A simplified analytic model of the multi-coil system configuration is developed, whereas the mutual inductance and the coupling factor are determined by numerical simulations. To validate the analytical and simulation results, an experimental setup was built. Both simulation and experimental results at a distance of 83% of the receiving coil diameter show that the proposed MISO coil system improves the received power and reaches at the same time a much better efficiency than that of two-coil systems. |

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.
