| Abstract | In order to realise wireless power and information transmission (WPIT), extra signal transmission coils are added in a traditional inductively coupled power transmission (ICPT) system, which results in a complicated structure and increases the volume and cost. Moreover, crosstalk existing between the power and signal channel makes it difficult to analyse and design. Therefore, WPIT technology based on the fundamental-harmonic component for a single-channel and two-coil ICPT system is proposed, in which the signal is transferred via the third harmonic component of the triangular current flowing in the transmitting coil. The working mechanism, crosstalk among circuits, parameter selection principle of signal detection channel are analysed, and the impact of load conditions on harmonic communication quality and that of signal transmission on efficiency are discussed. The experiment results show that the method can effectively simplify the structure, reduce the volume and cost, and fundamentally simplify the modelling, analysis, and design of the system, and high-quality power and information synchronous transmission can be achieved. |

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.
