Abstract :
According to the existed problem of neutral-point-clamped Multilevel-Inverter´s structure, the cause and influence factors of neutral-point voltage´s drift are analyzed, and a method is proposed to control neutral-point voltage with space voltage´s synthetic vector in the paper. Based on the software Simulink, the simulation model is established and the simulation experiment is carried out. The results show that the method´s feasibility and efficiency are good.
