| Abstract | A Three-Phase five level AC/DC Converter with Cascaded H-Bridge (CHB) Converter topology is presented to achieve unity power factor and improve power quality. The CHB active rectifier is an attractive topology that allows feeding of similar or different multiple DC loads. In this paper, the AC/DC converter is controlled in Synchronous Reference Frame (SRF) scheme, such that it draws a sinusoidal line current with unity power factor from the AC source. The SRF is adopted in the system to track line current command and output voltage reference. The system model and control algorithm are described. A Zero Current Injection (ZCI) solution is presented for voltage balancing of distinct dc buses in multi level CHB rectifier. This method ensures that the dc bus capacitor voltages converge to the reference value, even when the loads attached to them are extracting different amounts of power with acceptable load power limits. Multilevel Sine Pulse Width Modulated (SPWM) scheme is used to reduce the current harmonics in the input and obtain regulated DC output. The effectiveness of the proposed control algorithm is verified by the computer simulations and validated with 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.
