| Abstract | A new commutation method for a full-bridge current-source inverter is presented in this paper. During the commutation time, the four active switches are not simultaneously conducting. Instead, the two legs of the full-bridge inverter are in turn triggered on to provide the conducting paths for the load current. The steady-state load current can be reduced to zero during the commutation time. The residue energy stored in the parasitic inductance of the load is dissipated. And thus the voltage spikes resulted when the load current changes its polarity are reduced. The operations of the full-bridge current-source inverter are discussed. A prototype composed of IGBT power switches is implemented to output an ac current of which the amplitude is up to plusmn125 A. Experimental results show that the step change of the load current during the commutation is indeed reduced |

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.
