| Abstract | In this work a multilevel inverter based grid connected photovoltaic system is presented. It is used a T-type multilevel inverter. This inverter is based on a classic three-phase voltage source inverter. However, in order to increase the number of voltage levels, three extra bi-directional switches are used. These switches are connected between the three-phase terminals of the inverter and a common point of the two DC-capacitors. The inverter is connected to the photovoltaic panel through a DC/DC converter and to a three-phase transformer. The DC/DC converter and the multilevel inverter are controlled using a sliding mode controller. At the output of the controller associated to the multilevel inverter is used a vectorial modulator. This modulator will also be used to ensure the DC voltage balancing of the capacitors connected to the inverter. A maximum power point tracking algorithm associated to the photovoltaic generator is also presented. Several results are presented in order to confirm the characteristics of the proposed system. |

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.
