A parallel matrix converter system
2006 37th IEEE Power Electronics Specialists Conference, 2006This paper proposes a large-scale matrix converter system which connects two main circuits in parallel and in which the carriers operating each main circuit have a phase difference of 180 degrees. A matrix converter needs an LC filter, not only because it acts as a conventional filter which reduces high frequency ripples caused by the converter ...

Matrix converter control for DFIG
2013 IEEE International Conference on Emerging & Sustainable Technologies for Power & ICT in a Developing Society (NIGERCON), 2013The matrix converter is made up of a matrix of bidirectional switch elements. The output voltage control is achieved by switching between the allowed switching states using a predetermined sequence. Filters can be used to remove the unwanted high frequency components due to the switching.
