Abstract
This paper proposes a novel control method for the multiphase voltage regulators (VRs) to power the next generation of microprocessors. With a simple structure, this control can achieve multiphase current sharing, very fast transient response, and adaptive output voltage regulation. Simulation and experimental results show that the proposed control scheme significantly improves the performance, as compared with existing control methods.
