Abstract

Multilevel inverter is used to synthesize a near sinusoidal voltage. Powerquality is improved with the increase in number of levels. However, the number of switching devices and other components increase which would result in increase in cost and control complexity. To alleviate this problem, a multilevel inverter of hundred and twenty seven (127) levels with only ten switches and six diodes is proposed. The system uses a bypass diode technique with only one H-bridge for any levels. Simulation is carried out in Matlab for 127 levels and the output is figured out. The same set up is realized for seven (7) levels with the hardware components and the output is verified. The system yields better results when compared to earlier works with reduced control circuit complexity and cost. Further, the suggested topology reduces the number of DC sources, switches and power diodes.
