Abstract：Multilevel converter has been found widely application in high power drive system. In this paper, the development of the multilevel converter is reviewed, and the relationship between different topologies are analyzed, and then the rules which should be obeyed are summarized when the different topologies are deduced from the generalized topology. Based on this, two novel topologies are presented, and the operating concept and control algorithm are studied. Simulation results show the feasibility of the proposed topologies.
