The study includes the synthesis of a suitable averaged large-signal dynamic model for each topology and the design of nonlinear feedback controllers based in the input-output linearization approach. The modeling method is based on the extended describing functions, which approximate the resonant state-variables to sinusoidal functions with slow time-varying amplitude and phases. The proposed controllers provide some outstanding features as: zvs condition for a wide load range, fast transient response and robustness in relation to external parameter variations. The work is organized as follows: chapter 2 presents the different modulation method that provides zero voltage switch in a wider dynamic range. Also the steady-state characteristics based on the first harmonic approximation of each resonant circuit are presented. In the chapter 3 the modeling method is applied to three resonant topologies (series, cll-t and series-parallel lcc resonant converter) to obtain its averaged large-signal models. In order to verify the model prediction capabilities, a comparison of the resonant variables waveforms generated by the averaged models and the state space models has been carried out. Chapter 4 describes the design of nonlinear controllers for each resonant circuit and modulation technique based on the large-signal models obtained in chapter 3. The proposed controllers use linear sliding surfaces obtained by dynamic imposition, which allow the converters to follow a linear dynamic response when they are operating in closed-loop. Chapter 5 presents the results obtained with experimental prototypes which confirm the validity of the models and the proposed controllers. Finally, the conclusions of the work and the future investigation lines are presented in the chapter 6.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Modelos
