Abstract :
As the size and the cost of power semiconductor switches are decreasing, converter topologies with high device count are starting to draw more attention. One such type of converter is matrix converters. This paper proposes a new structure for three-phase to single-phase AC/AC matrix converters. The control strategy for this new kind of matrix converters is based on the minimum error between the measured and the forecast output voltages. Using this new structure, the output voltages have no limitation on the output frequency, and the amplitude and harmonic content of the output voltage is significantly less than that of the classical kind of matrix converter. The most important and valuable characteristic of this new algorithm and new structure is that even under unbalanced and significantly distorted input voltage waveforms, the output waveforms turn out to be reasonably clean and balanced.
