A New Switch Capacitor Multilevel Inverter With Partial Charging Switching And Reduced Components

Abstract

A multi-level inverter structure with capacitance switching based technology is proposed in the conducted study. The dominant feature of this inverter is that the obtained waveform of the output is similar to the sinusoidal wave. The purpose of this method is to apply the partial charging to obtain several voltage levels from each capacitor, which can diminish the quantity and capacity of the capacitors. To do this, only two capacitors are applied to produce 13- level in the suggested circuit. Moreover, the proposed framework is successfully fabricated along with evaluating the total harmonic distortion. In the following, a recommended switching method is introduced that is capable to heighten the derived voltage levels without increasing the quantity of elements. Simulation protocols are reported to validate the truthful operation of the suggested multi-level inverter.
