Abstract | The present paper investigates a novel type of voltage-clamped VVVF high-frequency power inverter comprising fast-switching SCR's and GTO's (or Power Transistors; PTR's) which provides power regenerating and voltage-clamped effects, and its useful modified circuit versions. The state-of-the art high-frequency inverter circuits proposed herein operate stably and efficiently in the frequency range of 10 kHz to about 100kHz or more and are suitable for the large-power high-frequency switching DC-DC converters. The basic working principle of the latest prototype of voltage-clamped VVVF high-frequency inverter is described for an equivalent load model under an automatic tuned tank circuit load, and its salient features are pointed out from a practical point of view. The steady-state performances of trial SCR-GTO hybrid voltage-clamped high-frequency inverter with VVVF control function are illustrated and discussed on the basis of frequency control characteristics, external load variation characteristics and voltage regulation characteristics. |

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.
