| Abstract: | DC-voltage balance is one of the key aspects that affects the reliability of three-level inverter and its electric drive system.Therefore,the influence of space vectors on the neutral-point potential fluctuation is investigated in this paper,and a real-time control method is presented to control the neutral-point potential fluctuation.It is verified by simulation results that the proposed control method is practicable. |

| Keywords: | three-level inverter neutral-point potential fluctuation space vector |
