Abstract | This paper proposes the model development of a packaged semiconductor power module, for use in a circuit simulation environment. Focusing on railway traction applications, it considers a state-of-the-art 6.5 kV insulated gate bipolar transistor (IGBT) module, taking into account the antiparallel connection of IGBTs and free-wheeling diodes, and including all main electrothermal and electromagnetic effects associated with the multichip structure. The description of semiconductor physics is coupled with self-heating effects; electromagnetic phenomena associated with the packaging, layout, and interconnections are also taken into account. To optimize the compromise between accuracy and computational effort, the device models are based on a mixed physical and behavioral description, and are scalable to be representative of a desired number of parallel devices and to allow for the introduction of parasitic elements, as required. Electromagnetic effects are modeled by means of equivalent lumped elements, extracted by numerical simulation of an accurate 3-D structural assembly model. The description of transient thermal phenomena relies on a finite-difference approach that considers the use of both essentially 1-D lumped equivalent models and fully 3-D distributed description. The model is validated statically and dynamically, against both data-sheet information and measurements; a selection of simulation examples demonstrates its usefulness and versatility. Although developed for a specific application scenario, the proposed approach is of general validity. |

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.
