| Abstract | A low cost utility interactive inverter is valuable to the residential PV or fuel cell distributed generations. This paper presents a low cost solution to the single-phase grid-connected inverters, including the inverter topology, filter structure, and the current control methods. The reason for choosing the proposed converter topology is given. A novel current control method using the combinatorial feedback of the grid current and the capacitor voltage is introduced for the inverter, so that a low cost non-damped or slightly damped LCL-filter can be employed to attenuate the switch frequency current ripple and the system can be optimized easily for minimum steady-state error and current harmonic distortions, as well as the system stability. The characteristics of the inverter system with the proposed controller are investigated. Simulations and experimental results on a 5kW fuel cell inverter are provided to verify the proposed solution and its control strategy. |

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.
