Summary:Active droop control of voltage regulators and point of loads is a preferred way of implementing adaptive voltage positioning to save motherboard space. This paper develops an improved model and design methodology for this control. The conventional model is explained and need for an improved model is described. Based on this improved model, a generalized design procedure, applicable irrespective of the modulation scheme, is developed. Experimental verifications on a five-phase/120-A prototype are presented to validate the design procedure. Results show that the loop performance and output impedance predictions of the model are accurate.
