In this paper, a modular cascaded H-bridge multilevel inverter for single-phase and three-phase renewable applications has been described. HCMMLI (Hybrid Cascaded Modular Multilevel Inverter) is one of the useful power electronic interface strategy for PV system The primary operation of single phase module and the cascaded hybrid inverter has been explained in this paper. The operation of symmetrical mode has been analyzed. The Nearest Level Control method of multilevel inverter topology is discussed. With this topology, less number of switches could be used which reduces switching losses and harmonic distortion. The size and cost of the system is reduced with the reduced power switches. In this paper, the main focus is on utilization of above discussed topology for several H Bridge configuration with equal and unequal magnitude of DC source. This configurations are considered to be symmetrical and asymmetrical. Here, in order to find an optimum arrangement with high quality output voltage, the comparison of symmetrical, binary asymmetrical and trinary asymmetrical topologies are analyzed.
