A Nine-Level Symmetrical Multilevel Inverter with Switches

Abstract

Due to the lower tensile low-distortion overall output voltage with power switch stress, the multilevel inverter (MLI) is popular. MLI does however have several semiconductor switches and therefore increases the complexity of the switches. New symmetric and asymmetric MLI structures are proposed in this report. According to experts, the proposed structures require less controlled switches, power diodes, and condensers than both conventional and recently proposed topologies. The size, cost, and complexity of the DC voltage sources, switches, and drivers can be decreased, while the total performance can be improved. Reducing stress with a high voltage switch. Moreover, scientists have explored several types of switches, power diodes, the need for a driver circuit, DC voltage sources, and blocking tension, and have compared the three available topologies (traditional, present and newer). Many pulse width modulation techniques are employed to produce switching pulses. Experimentally validated topology viability has been followed by extensive simulation study using MATLAB/Simulink.
