This paper presents a novel topology for cascade multilevel inverters. This topology consists of series connected sub-multilevel inverters units that each unit can produce fivevoltage levels. The new topology has the advantage of a reduced number of switching devices and DC sources compared to traditional configurations. Proposed topology can operates in symmetric an asymmetric states. Three algorithms for creating asymmetric states have been presented. The simulation results carried out by MATLAB/SIMULINK
