| Abstract | In this paper, junction temperature behavior of Si power MOSFET and SiC diodes when conducting significant current is investigated in detail by experiment and theoretical analysis. The dynamic variation and steady-state values of device junction temperatures when carrying different currents are studied. The results show that the device steady-state junction temperature versus current curve rises sharply after around 100°C and 150°C, for the Si power MOSFET and SiC diode, respectively. Maximum obtainable steady-state junction temperatures are found to be around 190°C for the MOSFET and 220°C for the SiC diode. The experimental results are well-matched by PSpice equivalent thermal circuit simulation and theoretical analytical calculation. While such limitation does not present as an issue for Si Power devices (as they are generally not expected to operate above 190°C), it could limit one's ability in exploring the intrinsic very high temperature capability of SiC power devices. System design approaches that can alleviate these limitations for the SiC power device are discussed and recommended. |

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.
