| Abstract | In pulse modulator systems, bouncers are used for droop compensation of the main capacitor voltage. In this paper, the control of an active bouncer in a pulse modulator is described and the charging via a main charging system is analyzed. Six interleaved bouncer modules are situated on the primary side in series to the main capacitor bank, forming together with a pulse switch the pulse unit. To reduce the system complexity, the pulse unit is recharged with a single charging source. The proposed methods are verified by converter measurements on a single bouncer module. Additionally, a repeatability analysis of the pulse unit is performed and dependencies on initial voltages and switching jitters are derived. It is shown that in case of an open loop control and a standard deviation of the initial main capacitor voltage of $σ_{VMain(t=0)}$ = 15 ppm and the initial bouncer input voltage of $σ_{VBin(t=0)}$ = 75 ppm a pulse repeatability of PR <; 100 ppm is achievable in 99.7 % of the time. |

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.
