Abstract
A controller receives a value indicative of a number of phases in a power supply to be activated for producing an output voltage to power a load. The controller utilizes the value to adjust a magnitude of at least one control coefficient associated with the power supply. The control can also use the value of the input voltage to adjust the magnitude of at least one control coefficient. The controller digitally computes values for the one or more control coefficients based on the received value indicating the number of phases in the power supply to be activated for producing the output voltage. Based on the adjusted magnitude of the at least one control coefficient, the controller produces control signals to control the number of phases in the power supply as specified by the value to produce the output voltage.
