| Abstract | In this study, we present an improved comprehensive model of power diodes. This model is based on the numerical solution of the ambipolar diffusion equation (ADE) by a modified finite difference method using MATLAB. The ADE is solved for all levels of injection instead of high-level injection only as usually done. Local physical effects such as conductivity modulation, emitter recombination, carrier–carrier scattering and lifetime control are taken into consideration. Temperature and self-heating effects are also included in the model. The proposed model has been validated against Silvaco mixed-mode simulations showing very good agreement with much less simulation times for our model. To be self contained, we also present a model parameter extraction methodology for power diodes given their experimental transient waveforms. |

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.
