Abstract—The present paper concerns the control of a multi level inverter in autonomous operation. The inverter is a 5 level H-bridge type associated to a suitable LC filter. To control the system output voltages, a feedback linearization algorithm is developed with unknown load. Simulation is carried out for either passive or active loads. The ability of the controller to follow perfectly the desired reference was tested on a passive load. For a load sensitive to voltage change, like an induction motor, the study shows that the controller maintains the output voltage to its rated value under severe conditions.
