| Abstract | In recent years there have been increasing demands for the power supplies of microprocessors to supply a high current at a low voltage while maintaining a favorable load response performance. This in turn requires inductors for use as dc-dc converters to have low winding resistance and low inductance. Consequently, these inductors now incorporate many vertical-structure parts due to low production costs. Assuming further miniaturization of electronic equipment and components, however, vertical parts are likely to be adversely affected by the expanding magnetic field that interlinks with the winding region. We performed magnetic field analysis on a new method of decreasing the interlinking magnetic fluxes in the winding region by improving the core structure and winding technique. It was found that, by providing a number of windings on a laterally structured core and by connecting them cumulatively, the magnetic fields induced in the gap areas could be removed from the winding region. This inductor proved to yield an outstanding low-loss performance when used as a dc-dc converter for high-frequency operation. |

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.
