Abstract
A multilevel structure with more than five layers has the potential to drastically diminish harmonic content. The number of levels increases the output voltage and power. Adding a voltage level necessitates the addition of a primary switching device to each phase.
The objective here is to create the seven-level H-Bridge inverter with the fewest switches possible. This circuit's output is delivered to the induction motor. Using this approach, we can adjust the speed of the induction motor while also reducing noise and vibration. This study focuses on increasing the efficiency of multilayer inverters and the quality of the output voltage waveform. With only seven switches, a new seven-level strategy is implemented. The MATLAB simulation has been completed, and the hardware has been constructed by using IGBTs for the seven switches of the seven-level inverter.
