Power electronic converters play a crucial role in low power Renewable Energy Generation Systems (REGS). This study proposes a novel use for a single-phase grid-connected one-capacitor boost multilevel inverter in REGS. Multilevel inverter systems are well-suited for medium and high power applications. This research introduces a novel boost multilevel inverter that is based on a single capacitor and has five voltage levels (2Vdc, Vdc, 0, -Vdc, -2Vdc). The suggested configuration of the formation consists of a single-phase system with one direct current source, eight switches, and one capacitor. In order to enhance its power production, the inverter operates according to the principles of charge-pump theory. This involves charging the capacitor in parallel and discharging it in series connections to provide a greater voltage output. The suggested setup involves straightforward control duties. To accomplish this, a level-shift pulse width modulation approach is used. In this strategy, the reference signal is compared with four carriers to drive the switches and create the necessary pulse pattern. The created inverter has many unique characteristics, including the use of a single dc-source and one capacitor, a small dimension, simple control needs, and the capability to enhance. The MATLAB software is used to model the system and construct a simulation to assess the performance of the five-level configuration grid linked solar system.
