Abstract :
The three-level technology of converters has the weak point of the neutral point voltage potential unbalance. This paper describes a scheme to control neutral point voltage variation in three-level converter. The scheme solves the problem by controlling the three-level rectifier. The parameters in it can be reconstructed and it avoids adding complexity to the inverter. The simulation at the last part demonstrates validity of the proposed scheme.
