Abstract | This paper presents a new single stage three level resonant power factor correction AC/DC converter suitable for high power applications (in the order of kilowatts) with a universal input voltage range (90-265 Vrms). The proposed topology integrates a boost input current shaper with a half-bridge three-level LCC resonant DC/DC converter. The converter operation is controlled by means of a combination of phase-shift and frequency control. The phase-shift between the switch gate pulses is used to regulate the DC-bus voltage to a specified level for all loading conditions, whereas, frequency control is used to tightly regulate the output voltage. An auxiliary circuit is used in order to balance the voltage across the two DC-bus capacitors. The input inductor operates in discontinuous conduction mode. The effectiveness of the proposed converter is verified for a 2.3 kW, 500 kHz converter with an input voltage range of (90-265 Vrms) and a DC output voltage of 48 V. |

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.
