| Abstract | This paper presents an in-depth comparison and evaluation of average models for nine-phase diode rectifiers, proposing a new model featuring improved static and dynamic characteristics exceeding by far those of previously existent models. The key to the proposed model is the representation of the dc load current by means of its Taylor series expansion. The analysis revealed a 10% and 3% average error reduction of the proposed model in steady state and transient conditions respectively, as well as an accurate calculation of the converter output impedance to less than 10deg and 1 dB phase and magnitude error. The paper shows too that average models of diode rectifiers and line-commutated converters are also subject to the sampling theorem limitations, i.e., their frequency response is limited to half of the averaging period. Finally, key steady state, transient and frequency response results are validated using a 2kW experimental prototype showing the high accuracy achieved by the proposed average model |

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.
