$v^1$ Concept: Designing a Voltage-Mode Control as Current Mode With Near Time-Optimal Response for Buck-Type Converters

This paper introduces the v
¹
concept that explains how by only measuring the output voltage, designers have information about almost every signal of the power stage. Following the v
¹
concept, 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.
