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 shar...
