| Abstract | In this paper, a wireless power system based on class E amplifier is constructed, and the mathematical model based on inductive coupling between transmitting and receiving windings are built subsequently. The values of some components for transmitter are optimized precisely according to the optimal working point of load resistance. Formulas for the optimal transmitter, receiver, and class E components are derived given a set of constraints on the load resistance, inductance values of the coupler, the phase angle and quality factor of load impedance, and drain voltage waveform. Moreover, the simulation is fulfilled to verify the method to calculate parameters. Using a separating transformer with a pot type ferrite core and a series-parallel arrangement for load impedance transformer, A wireless power transfer system based an open loop class E amplifier has been built and experimental results show that the system has desirable performance, including a power delivery of 4.2W with the distance is 10mm, and the peak efficiency of system is over 72%. |

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.
