| Abstract | This paper proposes a soft-switching technique applying to a single-stage single-phase ac to high voltage dc converter based on Cockcroft-Walton (CW) voltage multiplier circuit. Originally operating under hard-switching, the proposed converter improves switching characteristics by adding an auxiliary circuit for achieving soft-switching. The circuit operation principle of the proposed converter is presented in this paper. The design consideration for determining the values of circuit components used in the implementation is driven as well. For improving the line condition, power factor correction is applied to the proposed converter. Some conventional PFC control methods can be easily adapted to the proposed converter with few modifications. For convenience, this paper employs a commercial PFC IC to implement the controller for the proposed converter. The PWM signal generated form the PFC IC is modified by a simple digital circuit and then sends to the main and auxiliary switches in the power stage. A 500W/1200V prototype is built for test, measurement and evaluation. Finally, the experimental results demonstrate the validity of the proposed converter. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
