Abstract :
A design method using quantitative feedback theory (QFT) for robust control of current-mode PWM dc-dc converters is described. The proposed method considers both continuous and discontinuous conduction mode models (CCM and DCM respectively), taking into account large load perturbations. This technique results in a robust design insensitive to parameter variations and also to model changes
