| Abstract | According to the problem that differential mode circulating current exists in the three-level modular grid-connected photovoltaic system with LC filter, the equivalent model of differential mode circulating current was proposed in this paper. Differential mode circulating current was divided into two types according to different loops. The admittance curve of differential mode circulating current between frequency and leakage inductance ratio was analyzed, and the conclusion was made that the first type of differential mode circulating current is much larger than the second type. Then, the parallel scheme with LCL filter is used, and the inductance ratio is reasonably designed to reduce the differential mode circulating current effectively. A three-level modular grid-connected photovoltaic system rated 10kW was built, and simulation results and experimental results demonstrate the correctness of the model analysis and reduction methods of zero-sequence circulating current. |

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.
