Design a Three Phase 43-level Inverter Fed by Renewable Energy Source

Abstract

The issue of DC to AC inverters has gained interest due to the growing use and investment in renewable energy sources as a competitive power source. This paper presents efficient technique for producing an AC sinusoidal signal from DC power. The primary objective is to create a highly effective inverter that generates a pure sinusoidal AC signal with the least amount of overall harmonic distortion. MATLAB Simulink was utilized to develop and simulate an inverter for this purpose. Four asymmetric DC voltage sources and sixteen power switches are included in the inverter design in a [ 1:2:7:11]Vdc ratio to create an inverter with 43 levels (-21 to 21).The value output voltage of the single-phase 43- Level (THD-V)equal 0.70%,while a three-phase system's value are 0.63% .The main contribution is the establishment and demonstration of a sound methodology and model based on multilevel inverter with high power and reduce number of switch.
