Abstract | This paper presents a 5 kW boost converter with various passive/active snubbers for reducing current and voltage stress, and achieving high efficiency. The proposed converter includes a clamp branch diode and capacitor, a coupling inductor, and a PWM converter to function as active clamp. As compared to a conventional boost converter with a passive inductor-capacitor-diode (LCD) snubber, the proposed has the merits of low current stress imposed on the main switch, clamped switch voltage and limited reverse recovery current. In this study, three types of active snubbers, buck, boost and flyback, are respectively implemented with a boost converter. Theoretical analysis and experimental results have verified that the proposed circuit configuration is attractive for high power applications. |

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.
