Abstract
In this paper, a novel representation of the switch state of a
three-phase to three-phase matrix converter is presented. This approach,
based on space-vector notation, simplifies the study of the modulation
strategies, leading to a complete general solution of the problem and
providing a very useful unitary point of view. The already established
strategies can be considered as particular cases of the proposed general
solution. Using this approach, it can be verified that the space-vector
modulation technique, owing to the intrinsic two degrees of freedom,
represents the general solution of the modulation problem of matrix
converters. This technique can be considered the best solution for the
possibility to achieve the highest voltage transfer ratio and to
optimize the switching pattern through a suitable use of the zero
configurations
