Abstract
In this work we consider the developed scheme of multi-level invertor, which is collected on IGBT transistors. Transistor switching, which provides harmonicity of output tension, is calculated on each level. For verification the settlement data, the imitating model of multilevel inverter was constructed in MatLab program. The output curve tension received at the exit of multilevel inverter’s imitating model was spread out to harmonious components. It allowed investigating most precisely harmonious structure of the received multi-level inverter’s tension curve. For ensuring output tension with a sinusoidal curve, researches and calculations of a corner of switching for each source of the multi-level inverter are conducted. Calculation of switching corner for each source for eight, twelve and twenty-six step single-phase inverters is carried out. For each step the necessary level of tension is provided, it carries out the harmonicity the whole inverter’s output tension. Calculations were carried out in algorithm presented below, in this case for eight, twelve, and twenty-six step inverters.
