Abstract | A multi-mode operation for the three-phase photovoltaic (PV) power system with low-voltage ride-through (LVRT) capability is proposed. With the proposed multi-mode control strategy, the active power from the PV arrays can be continuously extracted by the interleaved boost converter during LVRT, whereas the maximum power point tracking operation can be quickly achieved after the grid fault clearance. In addition, the multi-channel boost converter with interleaved operation can increase power conversion efficiency while decreasing the input current ripple. On the other hand, the current amplitude limitation control of the three-phase inverter can provide maximum reactive power under rated current amplitude during the voltage sag period and output the demanded reactive/rated current ratio to meet different LVRT codes. A three-phase 5-kVA prototype PV converter is built and tested to verify the performance of the proposed multi-mode operation strategy and the LVRT capability. |

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.
