| Abstract | Pulsewidth modulated (PWM) inverters for power levels above 10 MW are presently the target of ongoing research. The implementation implies the series-connection of semiconductor devices, like GTOs or IGCTs, even if multilevel topologies are considered. Areas of application are flexible AC transmission systems (FACTS), transformerless reactive series compensators, HVDC transmission, static VAr compensators, and high-power AC drives. Existing problems are dynamic voltage balancing between the series-connected devices, snubber energy recovery and the transfer of gate drive power across potential barriers of more than 10 kV. The paper proposes an integrated solution for these problems. Experimental results from an inverter half-bridge composed of four IGCTs are presented. The respective device ratings are 4.5 kV and 4 kA. The DC-link voltage is 10 kV. |

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.
