Abstract :
The main aim of this paper is to present the possibility to solve one of the main problems of the multilevel inverter drives: the oscillation of the neutral point voltage, in the frame of sliding mode control. Using the robust futures of this control the selection condition for the DC line voltage and the power switch control is received and discussed. It is shown that in the frame of such control it is possible to eliminate the influence of the DC line voltage too.
