| Abstract | Using conventional methods with a rectifier on the secondary side of power adapter produces more heat. The heat generated, especially on high wattage power adapters, is even worse. An innovative high-speed controller, called synchronous rectifier MOSFET driver (or Driver), is designed to drive a power MOSFET in high current high frequency fly-back converters. The circuit does not require any ties to the primary side and derives its operating power directly from the secondary side. The circuit functions are structured by anticipating transformer output transition then turns the power MOSFET on or off before the transitions of the transformer to minimize body drain diode conduction and reduce associated heat losses. The advantages of using this solution that will be discussed are high efficiency, safe operation for lower operating temperatures, and ease of design and manufacturing |

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.
