Abstract
A controller for providing out of phase drive signals to a power converter having at least a first power unit and second power unit. The controller may comprise input circuitry adapted to receive a first signal from a first path and a second signal from a second path and provide an output signal in response to a difference between the first and second signals. The first signal may be representative of a current level of the first power unit during a first time interval and the first signal representative of a current level of the second power unit during a second time interval. The controller may further comprise output circuitry responsive to the output signal from the input circuitry to provide the out of phase drive signals to the first and second power unit.
