Abstract:
1. A method comprising: receiving a value indicative of a number of phases in a power supply to be activated for producing an output voltage to power a load; utilizing the value to proportionally adjust a magnitude of at least one control coefficient associated with the power supply; and based on the adjusted magnitude of the at least one control coefficient, producing control signals to control the number of phases in the power supply as specified by the value to produce the output voltage; wherein utilizing the value to adjust the magnitude of the at least one control coefficient includes: adjusting a first gain, the first gain associated with a proportional function in a PID compensator circuit, the proportional function producing a first signal based on the first gain; and adjusting a second gain, the second gain associated with a differential function in the PID compensator circuit, the differential function producing a second signal; the method further comprising: producing a sum based on summing at least the first signal and the second signal; inputting the sum into a filter circuit; adjusting a setting of a pole of the filter circuit based on the value; and utilizing an output of the filter circuit to produce the control signals.
