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 threelevel
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.
