| Abstract | The main structure of the proposed voltage source converter (VSC) for low voltage DC (LVDC) system is composed of three cascaded PWM rectifiers (CPRs) and a parallel DC-DC converter (PDC). High voltage AC grid is the input of the VSC. In order to ensure proper operation of the VSC, the control method should achieve output voltage sharing (OVS) among rectifiers in CPR, output current sharing (OCS) among DC-DC converters in PDC and low total harmonic distortion (THD) in VSC input currents. Master-slave direct current control (MDCC) is used to control CPR. The anti-interference ability of control system is robust by using MDCC without circuit parameters. PDC is controlled by three-loop control which is composed of outer common output voltage loop, inner current loops and current sharing loops. Simulation results show low THD in VCS input currents, good OVS in CPR and good OCS in PDC. |

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.
