Resonance-Based Normalization Theory for Analysis and Design of Resonant Power Converters

Abstract

This paper deals with a circuit modeling approach based on a normalization procedure in order to represent the system considering resonant parameters instead of real circuit parameters. The main advantages are the attainment of generalized solutions that do not depend on specifications, which allows the design of the converter without resorting to circuit level simulations. In this work, the fundamentals and the mathematical formulation of the normalized analysis are described. Furthermore, a multi-stage Class D-E DC-DC resonant converter is analyzed without simplifying assumptions used in other methodologies, such as, high loaded quality factor and fundamental component approximation. Experimental results are shown to verify the theoretical approach.
