| Abstract | The variations of parameters in magnetically coupled resonant wireless power transfer (MCR-WPT) system leads to system detuning problem. When the operation frequency is shifted from the resonant frequency of the system, output power of load (PL) will reduce greatly. The mathematical formulation of PL is similar to a multimodal function of the operation frequency. All the maximums of PL are needed to confirm the operation frequency. This study describes a dynamic niche artificial bee colony (DNABC) algorithm for locating all the optimums of multimodal function. By judging the increment of individual fitness, DNABC algorithm divides the solution space into peaky niche and candidate niche, and updates the boundary of niches dynamically. It transforms searching multiple maximum values in the whole solution space into searching one global maximum in each niche. Taking a 3-coil MCR-WPT system as an example, the simulation and experiment results show that DNABC algorithm is affected little by the number of population and has high convergence speed and high optimisation accuracy. |

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.
