| Abstract | This paper presents a comprehensive physical-based spatial analytical model for the turn-off behavior of a 6,5kV-IGBT and its implementation in the circuit simulator Saber. The basic idea is that the voltage slope at turn-off is determined by the sweep out of the plasma by the difference between the collector current and the MOS channel current. The resulting equations for the width of the space charge region, the electrical field and the collector-emitter voltage can be solved analytically. The switching process from the forward into the blocking state is calculated dynamically in contribution to the carrier distribution and changing electron and holes currents. The implementation of physical laws and measured parameters enable a simulation of the turn off behavior without fitting parameters and give insight into internal device behavior. Despite of complexity the model can be used as circuit simulator model, which enables more exactly conclusions for the IGBT gate control than common circuit simulator models. The created model shows a good performance even under very demanding switching conditions. |

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.
