Investigation of Hybrid Modeling and Control for DC-DC Converters

Abstract

This paper proposed uniform hybrid system models for second-order DC-DC converters working under continuous current mode. Contrast to the averaged and linearized models, no approximation is introduced to the modeling. The direct method of Lyapunov is used to analyze stability of the system and a new sliding mode control strategy is derived from the analysis. Simulation and experiment results are presented to validate the strategy
