| Abstract | Flyback switch-mode power supplies (SMPS) are popular for low-power and medium-power external power adapters due to their light weight and low cost. While the demand for more compact adapters for notebooks, tablets and gadgets is continuously increasing, there are physical limitations in the efficiency and power density that can be achieved using the Flyback topology. One major issue is the DC link capacitor, also known as bulk cap; its volume represents a big part of the adapter, its power dissipation is a major loss and its life expectation is the main factor in the reliability of the adapters. This paper introduces an innovative solution for reducing the value, the volume and the power losses of the bulk capacitor; as an extra benefit of this solution, the power factor of the adapter is also improved and the conduction losses associated with the front end of the converter are significantly reduced. |

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.
