Conception, Synthèse et Application d'une Nouvelle Commande Robuste par PID Fractionnaire pour Les Onduleurs Multiniveaux

Abstract : This thesis presents a new extension of multilevel inverters, called 'Multi Neutral Point' (MNP). This topology is deduced from Neutral Point Clamped (NPC) and Multi Point Clamped (MPC) structures. The advantage of this extension is twofold: the absence of clamping diodes and the possibility of operating on all the numbers of levels (even and odd). We have developed a simple command; we first present the command strategy for a three levels MNP, then for a five level MNP. We have compared the power losses in the power switches of an MNP and an NPC. The power losses for an MNP are far below those of the NPC inverter. For this inverter model, we have chosen a robust current control by a fractional PID controller. This control strategy can sharply reduce the amplitude and the phase errors between the reference current and the load one. This method requires the setting of various control parameters thanks to the principle of multiobjective optimization.'' In the end the set of converter-control command is validated by simulation and experimentation; the simulated and experimental results match very well
