| Abstract | A novel power factor corrector (PFC) composed of two-phase discontinuous conduction mode (DCM) boost PFCs and a coupled inductor is proposed in this paper. By coupling the two-phase boost inductors into the same magnetic core, both the circuit volume and the input ripple current are reduced. Therefore, the power factor (PF) value and the power density are improved. In addition, the output capacitor size can be smaller. The proposed topology distributes the input current and output current equally for the two phase modules. A cut-in-half duty cycle can decrease the conduction losses of the switches, and both the turns and diameters of the inductor windings, which help more to the reduction of the circuit volume. The advantages of a DCM boost PFC, such as natural zero-current-switching (ZCS) of the output diode, a natural PFC function, and the simplified EMI filter design, are maintained. Detailed analysis and design of the proposed topology, and the experimental results on a prototype with a 380-V output voltage and a 200-W output power are provided. |

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.
