| Abstract | In this paper a novel multiple gain switched capacitor (SC) DC-DC converter circuit with eleven switches and two flying capacitors along with a filter capacitor is presented. This converter is capable of powering electronic devices at different voltages in the buck or boost mode. Since proposed SC topology is inductorless, these converters can achieve multiple gains either in buck or boost mode at the output, with lower hardware cost, compact in size, light weight and less magnetic flux interaction. After a brief introduction about SC converter the operating principle and mathematical formulation of the proposed converter circuit is discussed in detail for each operating modes. PSIM simulation has been carried out to validate the design. An experimental laboratory prototype is implemented for verification of the circuit withsimple available transistor as switches and an astable multivibrator is used to produce the triggering pulses for controlling the switches. Simulation and experimental results concur for the converter working from a 12V dc input giving output options of 4V, 6V, 8V in the buck mode, 12V in the unity gain mode and 18V in the boost mode. |

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.
