Abstract (2. Language): 
In this paper, a new multilevel inverter topology using a reduced number of switches, insulated gate driver circuits and voltage standing on switches is proposed. The presented topology is a hybrid modular multilevel inverter. The operation of the proposed inverter is the same as the conventional three-level inverter. The proposed converter creates positive and zero voltages in phase. The proposed topology combines a three-phase inverter and sub single phase-units. This topology can be used as symmetric and asymmetric converter. One algorithm for determining the magnitudes of DC voltage sources has been presented in the asymmetric state. The validity of the analysis has been proved by simulation and experimental results with a laboratory prototype.
