Abstract
This paper presents a novel output voltage regulator in cascade structure under the consideration of both of the parameter and load uncertainties. It leads to the first-order closed-loop inner and outer loop dynamics in the low-pass filter form by the pole-zero cancellation through the active damping injection, which is the main contribution of this study. Moreover, it is proved that the active damping injection level determines the disturbance rejection capability of the closed-loop system. A 3-㎾ DC/DC buck converter confirms the actual advantages from these two contributions.
