| Abstract | This paper presents a soft switching converter with interleaved pulse-width modulation (PWM) scheme. There are two circuit modules in the proposed converter to share the load current. The interleaved PWM scheme is adopted to control two converter modules such that the input and output ripple currents and the current stresses on power switches and transformer windings are reduced. In each converter module, two forward converters with active clamp technique are adopted to further reduce the ripple current on the output capacitor and decrease the current stresses on transformer windings. The gate signals of two power switches in each converter module are complementary each other in order to realize the zero voltage switching turn-on of switches at the transition interval. Thus, the switching losses and thermal stresses of the semiconductors and transformers are reduced. All of these features make the proposed converter suitable for the dc-dc converters with high output current. Finally, experiments based on a 600W prototype are provided to verify the theoretical analysis. |

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.
