| Abstract | Based on the conventional forward converter, the transformer's magnetizing inductance is made small, and a reset winding of the transformer is moved to the secondary side, and furthermore, the anode terminal of the freewheeling diode is connected at a different point. Then a novel topology of DC-DC converter is proposed, and its power efficiency is predicted to be improved. This converter has both operations of forward and flyback manners, and both of two diodes in the output side are maintained to be ON for a portion of the switching period. This operation results in the zero ripple of the output inductor current. This novel converter is confirmed to have some prominent features of withstand-voltage reduction for the main switch and ripper reduction of the output inductor current. As a result, this converter obtains a higher efficiency over the conventional forward converter. This paper describes its basic operation, and analyzes the steady-state characteristics by means of the extended state-space averaging method. The analytical results are confirmed experimentally, and an experimental result of a high efficiency of 94% was obtained for the input voltage of 140V and the output load of 18V and 4A. |

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.
