| Abstract | Switched Capacitor Converters (SCC) losses are analyzed and the rules for the selection of SCC parameters (such as switch resistances, capacitors values and switching frequency) to meet specific efficiency requirements, are developed. This is done by first applying an advanced methodology for calculating the equivalent resistance (Re) of the SCC in general. The impact of each of the parameters on the equivalent resistance is then analyzed and the results are used to develop design rules to meet efficiency targets as defined. The paper clarifies an apparent paradox related to the role of switch resistances in SCC which seem not to affect the efficiency considering the fact that the efficiency is determined by the SCC voltage transfer ratio. The results of this study could help designers of SCC to select optimal values of the SCC parameters that will meet specifications. The analysis developed in this study can also assist users of SCC to better understand the characteristics and limitations of commercially available SCC. |

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.
