Abstract The neutral point (NP) voltage variation is studied; the relationship between NP voltage variation and the overlap is analyzed, in this paper. And a new SPWM control method for three-level (3L) inverter is proposed. A closed loop system is built by altering the displacement of the carriers in the vertical direction in the proposed method, and the control structure is simple. It is easy to make the NP voltage balance by adjusting the overlap. Simulation results indicate that the proposed method can get a good NP voltage control effect.
