Abstract :
This paper introduces the v1concept that explains how by only measuring the output voltage, designers have information about almost every signal of the power stage. Following the v1concept, it is explained how to design a traditional type-III voltage-mode control to behave like a current-mode control with near time-optimal response under load transients. This study is validated in simulations and experimentally on a 300-kHz buck converter.
