Multilevel inverter of reversing voltage topology has emerged recently as a very important technology in the area of medium-voltage high power energy control, due to lower EMI, requirement of less number of semiconductor power devices with less blocking voltage, lower THD percentage in output voltage, and less stress on insulation. This topology overcomes the disadvantages that a normal multilevel inverter has, like increased number of components, complex power bus structure in some topologies, and voltage balancing problem at neutral point. In this paper, the multilevel inverter with reversing voltage is implemented (which was previously proposed). This topology of inverter is first simulated using MATLAB simulation in open loop, and then PWM technique is introduced to have a control over the output RMS voltage; for these topologies the THD is analyzed. Then closed-loop control is implemented using fuzzy logic. The open-loop configuration of the circuit is realized in hardware and the results are analyzed.
