| Abstract | Recently, analog control is replaced by digital control in cycloconverter-fed adjustable speed drives. However, cycloconverter has many thyristors and control signals. Multi-CPU has to be adopted for its complexity. In this paper, main circuit is redesigned due to multi-phase. An interstar winding method is used in insulating transformers to supply 12-phase power. A 12-phase cycloconverter based on DSP with CPLD is proposed. The inner structure of CPLD is designed especially to generate heavy firing pulses composed of control signal distributor, counting time delay and pulses widening, and pulses distribution parts. Simulation and experiment results denote that a digital cycloconverter based on DSP with CPLD has the convenience of design and debugging, and has preferable control performance and high reliability |

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.
