| Abstract | This paper focuses on the study of a soft-switched unidirectional boost-type rectifier employing a snubber circuit, used as a front-end converter stage in high-power applications. The proposed rectifier operates with soft switching which results in high efficiency and low cost. The switching losses and electromagnetic interference (EMI) result in poor efficiency, therefore, soft switching techniques need to be developed to improve the efficiency. To achieve the desired result, the snubber circuit which consists of a lossless snubber switch cell and a resonant inductor, is introduced in the above-mentioned converter. The topology of the proposed converter is derived from the conventional T-type three-level boost rectifier. The circuit operation, theoretical analysis, and simulation of the converter in MATLAB/Simulink environment are carried out. Finally, a 10 kW laboratory set-up of the proposed soft-switched unidirectional rectifier is built. The experimental results obtained validate the theoretical analysis of the circuit. |

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.
