| Abstract | Based on the switching function algorithm of the traditional matrix converter, that of matrix rectifier (MR) is derived in positive and negative phase sequence with four-quadrant capability. Afterward that of MR under unbalanced input voltage conditions is also derived by detecting and using instantaneous values of input voltages. But the gained algorithm in the case is not fully suitable for the unbalanced conditions without any modification, such as amplitude unbalance, initial phase angle unbalance and waveform distortion. This is mainly because the constraints of switching function algorithm would be destroyed, even worse at high desired DC output voltage. The constraints include two aspects: the sum of relative switching functions for an output phase is always zero and the value of each switching function is within [0, 1]. At this point, a simple process method is proposed to meet the constraints to a large extent by means of regulating each switching function according to the actual unbalance before use. Eventually thorough simulations are performed with Simulink6.0 under balanced and unbalanced conditions, inclusive of input voltage and input current waveforms, output DC voltage waveforms, etc. The simulation results prove the theoretical analysis. |

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.
