| Abstract | This paper presents an AC/DC converter system utilizing an AC/AC direct converter and an inverter with a medium frequency isolating transformer. The operation of the AC/AC converter is based on soft commutation technique. Overlap time has been introduced for a proper zero current switching operation of the AC/AC converter. During operation, the current through the medium frequency transformer causes a voltage drop due to copper losses. These two phenomena result in deviations from the actual operation of the AC/AC cycloconverter. In this paper, a compensation technique is proposed by deriving the related formulas for nonideal operating conditions. With such compensation, the overall system will react dynamically to the changing conditions faster and the error in steady state operation is minimized. The simulation results verify the feasibility of the proposed compensation scheme for a better performance and faster dynamics. |

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.
