This paper presents methodologies for the structured modeling and analysis of dual-output dc-dc resonant power converters. The work is underpinned by a generalization of classical fundamental mode analysis (the most prevalent technique for the analysis of single-output converters) with a progression of increasingly accurate linear load-modeling extensions (at the expense of computational complexity) to accommodate converter output asymmetry and component parasitics when a dual-output rectifier is employed. Application of the technique, and the benefits afforded by the proposed modeling methodologies, are demonstrated through the analysis of a prototype dual-output converter, with a comparison of the results from both theoretical predictions and simulation studies, and experimental measurements from the commissioned converter.
