Abstract
A differential switching converter system is disclosed. The converter system includes a plurality of switching converters having at least first and second converters. The plurality of switching converters is coupled in a differential configuration across an output load. Each converter has at least first and second transistors configured to apply and receive energy to and from an energy storage element. The converter system also includes a controller, which is configured to control the operation of the first and second transistors of each converter. The controller synchronizes turn-on and turn-off of the first transistor in the first converter with that of the first transistor in the second converter. The controller also controls turn-on and turn-off of the second transistors in the first and second converters to provide first and second duty cycles, respectively.
