| Abstract | A dual-mode input voltage modulation (IVM) control scheme for a three-phase ZCS series resonant (SR) inverter fed three-phase voltage multiplier based DC-DC converter for X-ray power generator is proposed. The three-phase ZCS SR inverter is formed by connecting three single-phase ZCS SR inverters in parallel and delaying the gating signals by 120deg with respect to each other. It operates at constant frequency & duty ratio. The lower arms of all the three single-phase inverters (i.e. which make three-phase ZCS-SR inverter) are connected to a common holding capacitor $C_{H}$ and the voltage $V_{H}$ across it, is controlled by a control circuit. At the turn ON of the converter, the control circuit clamp voltage $V_{H}$ to 0V, causing inverter to see full input voltage and output voltage to rise with maximum speed. As the output voltage reaches 80% of target voltage value, the voltage $V_{H}$ is raised from 0V to $(V_{H})_{ref},$ thereby reducing the effective input voltage to inverter. As a result the rise rate of output voltage slow downs and the over shoot is prevented. Experimental results based on the laboratory scale-down prototype are presented to verify the effectiveness of proposed dual-mode IVM control scheme. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
