Abstract :
This paper provides a systemic review of today´s VRM controller architecture. The top-level building blocks of all known controllers are identified and they are the modulator, the compensator and the sensor. Novel concepts are then developed in these three areas for developing a high frequency, multiphase VRM controller.
