| Abstract | This paper presents a simple and effective supply voltage unbalance correction approach for a PWM rectifier and a new current controller based on integral variable structure control (IVSC). The current commands in the proposed approach are generated by making the positive sequence current command in phase with the positive sequence voltage and the negative sequence current command 180 degree out of phase with the negative sequence voltage. By choosing current commands in this way, constant dc-link voltage together with sinusoidal input current at unity power factor can be achieved. Integral variable structure current controller in stationary frame is used to provide robustness and achieve high performance current tracking in the face of system uncertainties and disturbance. The existence and stability of sliding mode is ensured by using a proper reaching law approach. The effectiveness of the proposed supply voltage unbalance correction approach and integral variable structure based current controller are validated through 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.
