| Abstract | Nowadays, low power factor (PF) is a serious problem that has gained more importance in power electronics area. In this study, a unity PF control (UPC) strategy for boundary conduction mode (BCM) buck–buck/boost PF correction converter is proposed. The proposed control strategy can achieve high PF and low total harmonic distortion by utilising the input and output voltages to modulate the on-time of both buck and buck/boost switches. The operating principles and comparative analysis of BCM buck–buck/boost converter with conventional non-UPC and UPC are analysed. For verifying the effectiveness of the proposed control strategy, the experimental verifications are carried out from a 100 W universal input prototype. |

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.
