| Abstract | To address the problems of traditional frequency tracking, such as falling into a local optimum, oscillation near the optimal point, and contradiction between tracking speed and tracking accuracy, an improved perturb–observe method based on component drift parametric scanning is proposed. An inductive contactless power transmission system with LCC/S third-order compensation topology is employed as the research object. First, the relationships between the output voltage and frequency under component drift parametric scanning are given by theoretical deduction and calculation. Then, a reasonable working frequency band is intercepted, and the improved perturb–observe method (including start, end, step, and anti-death cycle judgement) is used to track the optimal working state adaptively. Finally, the correctness of the proposed theory and method was verified by simulations and physical experiments. |

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.
