Modelling and control of a DC–DC multilevel boost converter

Abstract

This study proposes several dynamic models for a DC–DC multilevel boost converter. A full-order non-linear dynamic model, a reduced-order non-linear model and a small-signal model are derived. These models are based on the equivalent circuits that depend on the switching states of the converter. In addition, an input–output feedback linearisation controller is derived and implemented. The stability of the closed-loop system is analysed. A Linux-based real-time software is employed for obtaining the experimental results of the closed-loop system.
