A Study on the transient response in the switching regulator

스위칭 레귤레이터에 있어서 과도응답에 대한 연구

This paper investigated the effect of right half plane zero on the transient response in the buck-boost DC-DC converter. And it is clarified that the damping ratio decreases gradually by increases of the feedback loop gain and the regulation system of the converter becomes unstable. From the result, we obtained the stability region about the duty ratio and the output current by evaluating the feedback loop gain.
