HIGH-EFFICIENCY FIVE-LEVEL BOOST MULTILEVEL INVERTER FOR GRID-TIED SOLAR SYSTEMS

Abstract

The voltage is insufficient. Power electronic converters are employed in energy-changing systems to generate energy that is sustainable. This research addresses an innovative REGS application that utilizes a single capacitor boost in a multilayer inverter that is connected to a single-phase grid. Multilevel inverters are advantageous for medium- to high-power applications. This article introduces a novel boost multilevel inverter that necessitates only one capacitor and has five levels: 2Vdc, Vdc, 0, −Vdc, and −2Vdc. The single-phase configuration is comprised of eight switches, one capacitor, and one DC source. The charge-pump design of the inverter results in a significant increase in power. This theory contends that the output voltage is increased by the charging and discharging of series and parallel capacitors. By comparing the reference signal to four carriers, levelshift pulse width modulation generates the appropriate pulse pattern. This straightforward method regulates the valves in the manner depicted. The inverter is distinctive in that it is compact, user-friendly, and requires only a DC source and capacitor to operate. Additionally, it provides a boost. MATLAB is employed to generate system models. The operation of the new five-level gridconnected solar system is verified by this simulation
