The purpose of this thesis is to present a novel controller structure for scalable switch-mode power supplies targeting low power applications. The design employs masterless control, where each phase is responsible for its own control in a multiphase system. The controller is capable of automatically configuring itself to work with a single phase system or a multiphase system. The configuration process allows each controller to determine the number of phases in the system, as well as to synchronize and sequence the phases. With this architecture, the same controller design can be used in many types of applications requiring different numbers of phases, resulting in a decrease in cost and design effort. The proposed design has been verified experimentally on FPGA and IC implementations.
