Three recently developed control methods for voltage regulator modules (VRM), namely, V/sup 2/ control, enhanced V/sup 2/ control, and enhanced V/sup 2/ control without output voltage dynamic feedback, are analyzed and compared in this paper. All three methods utilize the output voltage-switching ripple for pulse-width modulation, hence are collectively referred to as ripple-based control. A general modeling method based on the KBM (Krylov-Bogoliubov-Mitropolsky) ripple estimation technique is… CONTINUE READING
