This paper proposes a synchronized switching technique to remove unexpected output pulses in Hybrid Active Neutral-Point Clamped

(ANPC) inverters. The unexpected output pulse is generated at zero intersection point of the output voltage. Whereas, the reason of

this pulse is due to the sudden effect of the deadtime on the switching time, in addition to another causes such as; the characteristic

of digital calculation and etc. The unexpected output pulse distorts the output voltage, output current, and degrades the efficiency

of the hybrid ANPC converter. Moreover, the unexpected output pulse may stress the switching devices as this pulse has momentary

metrics. Therefore, the unexpected output pulses have to be removed. In these regards, A synchronized switching technique is

proposed in this paper, while the proposed method is verified by simulation results.
