Abstract
A direct AC to AC converter includes a modulation stage, a transformer and a de-modulation stage. The modulation stage is configured to convert an AC input voltage with a first frequency into a bipolar PWM voltage with a second frequency, wherein the second frequency is higher than the first frequency. The transformer has a primary winding and secondary winding, wherein the primary winding is coupled to the modulation stage to receive the bipolar PWM voltage. The de-modulation stage is coupled to the secondary winding of the transformer and configured to convert the voltage across the secondary winding of the transformer into an AC output voltage with the first frequency.
