Hybrid Wiener-Hammerstein Structure for Grey-Box Modeling of DC-DC Converters

Abstract

In this work a generic hybrid model for dc-dc converters is proposed. The protections and remote control functions are managed by the logic system (event driven behaviour) and the power stage and control is modelled by a Wiener-Hammerstein structure. The model is oriented to be parameterized based on the information provided by manufacturers in their datasheet and it is able to predict power consumption, efficiency, system stability and large signal behaviour including inrush current, protections, start-up and remote on-off control.
