| Abstract | Insulated Gate Bipolar Transistor (IGBT) has the advantages of high rated voltage, high rated current, high switching speed and easy to drive. But a single IGBT still cannot meet the needs of the high-voltage converters at present. IGBT series and parallel connection can greatly extend the application of IGBT because it can effectively improve the system voltage and current capacity. Generally, the volume of high voltage IGBTs series connection converter is large because of the insulation and thermal performance requirements. It means that the bus bar structure is complex, and the stray parameters of the commutating loops, especially the stray inductance, will significantly influence the switching processes. It becomes one of the key points for the safe operation of the converter. In this paper, the design principles for complex physical bus bar are presented. Based on the finite element analyses, the bus bar structure of a high voltage IGBTs series connection experimental platform is designed and improved. The performance of the improved bus bar structure is verified by simulations and experiments. |

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.
