| Abstract | Space vector PWM (SVPWM) schemes for high power current source rectifier (CSR) normally produce low order harmonics and sub-order harmonics due to the low switching frequency and the drifting of synchronization between the PWM waveform and the CSR input frequency. To provide a synchronized PWM and achieve best harmonic performance, different space vector sequences suitable for a current source converter (CSC) are investigated in this paper. Details on how to achieve the waveform symmetries with minimum switching frequency for each sequence are discussed. A thorough comparison of the harmonic performance of different space vector sequences is carried out. In addition, two synchronization methods, namely a PWM frame regulation method and a direct digital phase-locked loop (DPLL) synchronization method are proposed. Both methods are equally effective in providing tight synchronization of the PWM waveform with the CSR input frequency. The space vector sequence investigation and the developed synchronization methods are verified in simulation and experimentally using a 10 kVA GCT based CSR prototype. |

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.
