| Abstract | In this paper, a short-circuit protection of an IGBT, based on current measurement is proposed. The IGBT collector current estimate is obtained by filtering the voltage between the auxiliary emitter and the power emitter terminals of an IGBT module. The proposed scheme utilizes a large bandwidth analog circuit which enables to the detect fault current regardless of the current slope. According to the experiments, the proposed circuit can detect faults before desaturation of the IGBT, which is a major benefit compared to the traditional methods based on IGBT saturation voltage measurement. |

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.
