| Abstract | This paper presents a detailed study on the switching process of a MOSFET-snubber-diode (MSD) configuration commonly used in power converters. An analytical model which takes critical parasitic elements and the interactions between gate drive circuit and power circuit into consideration is derived to evaluate the switching characteristics. The influence of parasitic elements and important circuit components in terms of power loss, ringing effect and device stress is discussed under two different conditions for the determination of current slew rate. Based on this work, guidelines are given for the design of high-frequency switching circuits with tradeoff between power loss, oscillation and device stress. The analysis has been successfully verified by the experimental results of a 750W boost converter. |

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.
