| Abstract | This paper proposes a mean active power control for pulse-width modulation (PWM) rectifier based on model predictive direct power control (MPDPC). Conventional MPDPC can achieve good steady state performance and quick dynamic response by minimizing a cost function relating to power errors. However, in two-level PWM rectifier, there are only eight discrete voltage vectors, which restricts the performance improvement of conventional MPDPC. The sampling frequency has to be high to achieve good steady state performance. As zero vector produces relative small power variations, this paper tries to incorporate the zero vector during one control period to achieve further steady state performance improvement. Only a fraction of control period is allocated to the non-zero vector obtained from conventional MPDPC and the duration is determined based on the principle of equaling the active power to its reference value in one control period. The presented experimental results prove that the proposed method produces lower power ripples and less current harmonics, while the dynamic response of conventional MPDPC is reserved. |

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.
