A design method for switched observers is presented. Global convergence of the switched observer is addressed in the case of a persistently exciting control signal. Hamiltonian modelling is used in the observer design. The observer is applied to a Series Loaded Resonant converter. A global model of the converter is given. Simulation is performed for illustration of the convergence properties.
Keywords: Convergence of observer, Switched systems, Lyaponov methods, Nonlinear analysis, Converter, Modelling
