ABSTRACT:
A method for controlling the output of a switching power converter to account for high and low current loads is disclosed. A reference voltage is generated with a voltage reference generator representing a desired DC output voltage for the power converter. Then the DC voltage output of the power converter is sensed with a digital control system and generating switching control signals to control the operation thereof to minimize the difference between sensed DC voltage and the reference voltage. The current through the power converter is then determined and the operation of the voltage reference generator controlled to set the value of the reference voltage to a level that is a function of the sensed current so as to anticipate future current loading.
