Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis paper proposes a simple and systematic procedure for identifying averaged large-signal models of resonant converters. The nonlinear behaviour of the converter is modelled via Hammerstein models, i.e., the model is represented by a static nonlinearity, followed by a linear transfer function. The parameters of the approximating structure are identified from input-output noisy data, with the application of modulating functions method. PSpice simulations and experimental tests are run for an exhaustive and accurate validation of the proposed methodology. A relevant result is that the technique allows an easy modelling in the critical case of resonant converters, where traditional averaging techniques fail.
