Investigation of the effect of the gap at the zero-crossing point of PWMs creating the first level voltage in a multi-level inverter

Using multi-level inverters in converting direct current to alternating current is one of the most demanded and used methods. It is one of the techniques that can be used to create the first level voltage ground by setting the PWM operating times at the zero point grossing from the positive and negative cycles to the gate while creating a multi-level voltage with inverters. In this case, it affects the quality of the generated voltage. Therefore, this article examines the effect of variation in
