Cascaded H Bridge 7-Multilevel Inverter Multilevel inverter, a power electronic device which can transform the level of dc voltages from lower to preferred ac voltage.  Optimized H-bridge 7 level multilevel inverter is a technique having increased number of switches through which 7 levels of voltage are generated at output.  It helps us to increase the output power of the inverter and further lowering the harmonics.  The H- Bridge technique is one of the successful techniques for the development of multilevel inverter as compared to other techniques, the H- bridge technique helps in decreasing the overall complexity of the circuit and reducing the switching loss
