Modélisation et Conception d'un Modulateur Auto-Oscillant Adapté à l'Emulation d'Organes de Puissance

Abstract : The work presented in this thesis talk about the optimization of the structure and the control of power emulating systems, called Actives Loads.
In order to display very good dynamic performances as well as a very great robustness, these Active Loads use a Resonant Current Controller (RCC) and a Resonant Voltage Controller (RVC).These processes are self-oscillating regulators and are thus by nature strongly non-linear. Also, for an optimal application of these processes to the Load Activates, the first point presented in this thesis is the modelization of these regulators and the identification of the possible problems, due to their non-linearities. It is then appeared that synchronization phenomena and switching frequency instability can appear if some conditions are not well respected. The second point of this work is the generalization of these modulation processes to any systems, based on a sliding mode control. So, a new structure of Resonant Voltage Controller is proposed, more efficient for the Active Load applications. The experimental results obtained on an Active Load prototype show the very great performances of this new process, thus contributing to the improvement of the quality and the precision of old and new generations of Active Loads.
