Abstract
This paper presents a new algorithm for three-phase to single-phase AC/AC matrix converters. This method is based on the minimum error between the real and the forecasted output voltages. By this new method, any favorable output with variable frequency and amplitude may be produced. The most important characteristics of this new algorithm is that even under unbalanced and significantly distorted input voltage waveforms, the output waveforms turn out to be reasonably clean and balanced. Also the amplitude of the output voltage obtained by this method is up to /spl radic/3V/sub i/. Using this new control method, it is ensured that the switches do not short-circuit the voltage sources, and do not open-circuit the current sources. Another advantage is that the converter designed by this new method has very low loss.
