| Abstract | In this study, the switching mode and working waveform of dual active bridge (DAB) converter under triple phase-shift modulation scheme is analysed, and an ALL-ZVS (zero voltage switching) control strategy of all devices for full-power range with voltage transfer ratio M > 1 is proposed. First, a feasible control domain of ALL-ZVS is derived by analysing the constraints of the control variables of ZVS for all switching devices under different operating modes. On this basis, an ALL-ZVS control strategy of current RMS quasi-optimisation under the condition of M > 1 is proposed with the existing inductor current RMS optimisation control algorithm. It can be concluded that the proposed control strategy not only eliminates the switching loss, but also reduces the conduction loss, greatly improves the efficiency of the DAB converter. Finally, an experimental platform is built, and the experimental results verify the correctness and effectiveness of the proposed control strategy. |

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.
