Modeling and analysis of a multi-output cuk converter

Abstract

A small signal network model for an experimental high frequency triple-output Ćuk do-to-dc converter system is developed in analytical detail including provisions for its unique ramp slope control regulatory circuitry, magnetic coupling between selected port inductances, and scaling transformer inductive effects. Results of empirical and computer simulations of a representative 200 KHz, 55W design are discussed along with recommendations for dynamic operational improvements.
