Abstract
The invention relates to a method for controlling a matrix converter with nine bi-directional power switches arranged in a 3×3 switch matrix. Four active switching states and one zero voltage switching state and the associated time intervals are calculated per modulation interval using space-vector modulation. The calculated interval of the zero voltage switching state is distributed to at least two of a total of three available zero voltage switching states, thereby eliminating or at least significantly reducing output voltage errors of the matrix converter.
