ABSTRACT:
A method and system that uses an anticipatory signal to pre-adjust the output of the power supply to compensate for an upcoming load change, thereby minimizing the voltage deviation at the load. A control circuit, such as a processor, controlling the system generates an anticipatory signal indicating an upcoming change in the load that is input to the power supply. The power supply, in response to the signal from the processor, adjusts the output of the power supply accordingly to compensate for the upcoming load change. When the system performs the operation that results in the load change, the power supply output has already been adjusted accordingly and the deviation of the load voltage caused by the change in the load is minimized.
