This paper presents a neutral-point voltage balancing method for three-level inverter systems using a time-offset estimation scheme.
The neutral-point voltage is balanced by adding a time-offset to the turn-on time of the switches. If an inaccurate time-offset is
added, the neutral-point deviation still remains. An accurate time-offset is obtained through the proposed time-offset estimation
scheme. This method is implemented without additional hardware, complex calculations, or analysis. The effectiveness of the
proposed method is verified by experiments
