Abstract—This work presents an analysis of fluctuating input voltages of the DC source of voltage three-phase inverter at three levels. Indeed, the two voltages have an imbalance between it. We obtain an output voltage of the inverter at three levels asymmetric and whose non-zero means value. To minimize this imbalance we propose a solution that involves inserting the terminals of each capacitor, a bridge balancing said bridge clamping. The simulation results are quite satisfactory

Index Terms—Neutral-Point-Clamped-(NPC), three level inverter, Pulse-Width-Modulation (PWM), clamping bridge, three level rectifiers.
