Abstract:
A switching converter system, comprising:a plurality of switching converters having at least first and second converters, said plurality of switching converters coupled in a differential configuration across a load, each converter having at least first and second transistors configured to apply and receive energy to and from an energy storage element, where said each converter is configured to regulate energy transfer from input to output while maintaining a constant output level within load limits; and a controller to control said at least first and second transistors of said each converter, said controller operating to synchronize turn-on and turn-off of said first transistor in said first converter with that of said first transistor in said second converter, said controller also operating to appropriately control turn-on and turn-off of said second transistors in said first and second converters to provide first and second duty cycles, respectively, said controller operating to substantially reduce ripple in said constant output level.
