Abstract

A robust model-following regulator for boost dc-dc converters with average current mode control is proposed in this paper. The aim of the proposed circuit is to reduce the closed loop output impedance and audiosusceptibility of the converter without the need of a high bandwidth in any of the resulting regulation loops. The robust model following average current-mode control regulator (KMFACC) maintains proper stability in a wide range of operation points. A systematic design procedure is explained. In order to validate the concept, a 24V-100W, 100 kHz dc-dc converter has been designed and experimentally tested.
