Abstract :
The maximum input-output transformer ratio, or output voltage ability, of direct AC-AC PWM converters is explored. An intrinsic limit, independent of the control algorithm, is found. A novel converter control algorithm is discussed that achieves the maximum output amplitude and displays some interesting features. The implementation of AC-AC converter control using feedback techniques is considered, and a feedback-based control algorithm is proposed.<>
