Abstract | This paper presents a hybrid current control scheme to minimize the even order harmonics at the dc link voltage and odd order harmonics in the line currents under the distorted and unbalanced supply voltage conditions. The hybrid current control scheme consists of a conventional PI and a repetitive controller (RC). Based on the mathematical model of the three-phase PWM boost rectifier in the positive and negative synchronous rotating frames, the influence of the distorted supply voltages on the line side currents has been investigated from the analytical point of view. The control task is divided into: (a) dc-link voltage harmonics control and (b) line side current harmonics control. In voltage harmonics control, a reference current calculation algorithm has been derived accordingly to ensure that the dc link voltage is maintained constant and the supply side power factor is kept close to unity. In current harmonics control, a plug-in repetitive controller is designed to achieve low THD line currents of the three phase PWM boost rectifier. The proposed analysis and hybrid current control scheme have been validated by experimental test results on a 1.6 kVA laboratory based PWM rectifier. Test results obtained confirm that the proposed control scheme enhances the performance of the PWM rectifier over the conventional one. |

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.
