| Abstract | This paper presents capacitor voltage balance control methods for hybrid cascaded H-bridge inverter with single DC source to remove higher order of harmonics, the power quality is therefore improved with low THD of output power for utility interactive inverters. In addition, a new control strategy based on voltage frequency regulation is proposed in this paper to achieve faster and smoother transition from grid-connected mode to stand-alone mode. For sensitive and mission critical local loads, a seamless transition between two operation modes is very valuable, especially for the transition from grid-tied mode to stand-alone mode in the case of utility fault. The proposed method not only implement fast transition, the load voltage waveform also becomes continuous during transients. The proposed control methods can be easily applied for multi-bus micro-grid control system with least modification. The simulation and experimental results of single-phase utility interactive inverter confirmed the validity of proposed control algorithms. |

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.
