| Abstract | To improve the coupler misalignment performance, this study proposes an LC–CLC compensation topology for high-power and long-distance capacitive power transfer system. The LC circuit in the transmitter and the CLC circuit in the receiver are adopted as the resonant tank for the capacitive coupler. The fundamental harmonics approximation method is employed to analyse the system working principle. Considering the misalignment of coupler, the characteristic of output power is provided against the variation of coupler capacitance. A 1 kW CPT system with 150 mm transfer distance is set up to validate the proposed compensation circuit under various misalignment conditions. The experiment results show that the system can transfer 1009 W output power with 90.56% DC–DC efficiency at 150 mm transfer distance when the coupler is well aligned. When the misalignment is 325 mm, the variation of the output power is only 10.6% in X-direction and 15.2% in Y-direction. The proposed system can achieve high anti-misalignment performance. |

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.
