| Abstract | This study presents an improved dead-beat control method for three-phase pulse-width modulation rectifier of the switching power supply under source-voltage harmonics and unbalance disturbances. First, a reference currents extraction method and an active negative sequence currents injection method for the dead-beat control are presented to suppress the input harmonic currents and the second harmonic voltage of the DC-link voltage in the rectifier. Then, active disturbance rejection control is presented to substitute for the PI control, which can improve the transient response and strengthen the antidisturbance ability of the rectifier. Finally, to improve the efficiency of the power supply, two auxiliary inductors are introduced to realise soft switching of the DC/DC converter, which is an idea of taking the rectifier and the DC/DC converter as a whole. The feasibility and superior performances of the presented control methods and topology have been validated by the experimental results. |

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.
