LOPEZ-ROBLES, E.; RODRIGUEZ-RIVAS, J.J.; PERALTA-SANCHEZ, E.  e  CARRANZA-CASTILLO, O.. Voltage regulation of a matrix converter with balanced and unbalanced three-phase loads. J. appl. res. technol [online]. 2015, vol.13, n.5, pp.510-522. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2015.10.003.

This paper addresses the design, simulation and experimental validation of a voltage control for a three-phase to three-phase Matrix Converter working under balanced and unbalanced resistive loads. The converter is based on bidirectional switches and space vector pulse width modulation is used to control their turn-on and turn-off times. Tracking and repetitive controls are designed and implemented; having this last one a major impact on the performance of the output voltage regulation for balanced or unbalanced loads. The experimental control setup is comprised of a field programmable gate array board, a digital signal processor and a graphics interface board.
