| Abstract | Voltage sags or short term reductions in the voltage levels constitute 68% of all power disturbances. Voltage sags are becoming crucial problems in many process industry plants as well as in rural customers, resulting in lower production and serious equipment damage. A possible method to compensate for voltage sags is to install an AC-AC boost converter that is capable of compensating at a much higher bandwidth than the typical voltage sag event. The AC-AC boost converter of this paper incorporates the use of bi-directional insulated gate bipolar transistors (IGBTs) in a relatively well-understood DC-DC boost converter topology. Most voltage sags are due to a faulted circuit or a major increase of load current. The resulting neutral return current produces an increase in the measured voltage. On a half cycle-by-cycle basis, the peak voltage can be used as feedback where the converter can maintain regulated supply voltage to the end user. Simulation results show that a three-phase AC-AC boost converter may sense and improve the voltage sags and power quality quickly due to the high-speed IGBT switching operations. |

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.
