V1 Concept Designing A Voltage-Mode Control As Current Mode With Near Time-Optimal Response For Buck-Type Converters

v¹Concept: Designing a Voltage-Mode Control as Current Mode With Near Time-Optimal Response for Buck-Type Converters

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.
