| Abstract | A novel dual active clamp forward topology with interleaved series input parallel output (ISIPO) structure is proposed here. The ISIPO active clamp forward converter enables the converter cells to share the input voltage and output current. The interleaved operation can diminish the output current ripple in the output capacitor. The output capacitance of switching devices and the resonant inductance are utilised to realise the resonance at the transition interval of switches such that the zero-voltage-switching operation for all switches can be achieved. Moreover, the energy stored in the transformer leakage inductance is recycled such that the voltage stresses of switching devices are reduced. All these features make the proposed converter suitable for the DC–DC converters with high input voltage, high output current and high-efficiency applications. The operating principle and design considerations are provided in detail. Finally, experimental results based on a 240 W(12 V/20 A) prototype with an input voltage of 400 V are presented to verify the theoretical analysis and circuit performance. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
