INVESTIGATION AND DEVELOPMENT OF A MULTILEVEL INVERTER WITH A 29-LEVEL REDUCED SWITCH COUNT

A novel multilevel inverter design for electric vehicle applications is presented in this research. In order to generate the necessary twenty-nine levels of output voltage and current waveforms, this multilevel inverter is developed using ten power switches and four distinct asymmetrical DC sources. Pulse width modulation is the most often utilized control method in multilevel inverters. This multilevel inverter uses sinusoidal pulse width modulation to remove low order harmonics. MATLAB is used for simulation, and a resistive load and resistive-inductive load is used for testing. A 210V, single phase, 29 level proposed architectural prototype uses MOSFETs as switching devices. In the hardware configuration, IRF840 MOSFETs are used. For inverter switches, the Ardiuno micro controller generates the gate signal. To achieve a twenty-nine level output waveform, typical multi-level inverters require a greater number of power components, which raises switching losses, costs, and harmonic distortion. By using 10 switches, the suggested inverter greatly reduces switching losses, low order harmonics, and switching costs, which in turn lowers overall harmonic distortions
