Multilevel power electronic converter has wide range of applications. In multilevel power electronic converters the output can be synthesized by combining several DC voltage sources. Cascade H-Bridge multilevel inverter generally requires more number of DC sources. An alternative option is to replace all the DC sources feeding H-Bridge cells with capacitors, leaving only one H-Bridge cell with a real DC sources. But balancing the capacitor voltage is challenging. In this paper a new control method for cascade H-bridge multi level inverter fed with only one independent DC source is presented. Simulation results support the proposed control method.
