Abstract | In this study, the performances and features of a two-phase converter with low switch voltage stress and its derivative converters are investigated thoroughly. As compared with the traditional boost converter, the voltage stresses of switches and diodes of the two-phase converter are much lower; thus, the switches and diodes with low-voltage ratings can be used, which reduces the conduction losses. Moreover, the switches are not floating, and the input and output terminals have common ground; hence, no isolated driver is required. In addition, by utilising the ampere–second balance principle, the proposed converter can achieve current sharing without any extra control circuit, leading to simple circuit structure. In the two-phase converter, the capacitors are used not only to realise automatic current sharing but also to further improve the voltage gain. In addition, because of the advantages of the two-phase converter, many types of converters are derived from the two-phase converter. Eventually, the operating principles, mathematical deductions and experimental results for the two-phase converter are given to provide its effectiveness. |

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.
