From the perspective of the current relationship, the reason of midpoint potential fluctuations for three-level inverter was analyzed. And based on redundant small vectors compensation, the action time correction methods for the basic voltage vectors and the original fundamental voltage vector have been proposed. Finally a simulation model was built in MATLAB for analysis, which showed that the three-level neutral point potential fluctuations can be suppressed effectively by the midpoint potential compensation algorithm.
