Abstract
A method is provided for implementing a three-phase pulse-width-modulated alternating current voltage regulator including six four-quadrant switches, wherein each four-quadrant switch includes two two-quadrant switches. Three series branches, each series branch including one four-quadrant switch, and three shunt branches, each shunt branch including one four-quadrant switch, are provided. To obtain a desired converter state, the two-quadrant switches in the series and shunt branches are turned on or off in a predetermined sequence.
