| Abstract | ||
| The paper introduces a five-level double-boost switched capacitor inverter configuration which is useful for the application of (PV) systems. The basic construction of the circuit consists of six IGBT switches, one diode, a single capacitor, and a DC supply to produce five levels of the inverter's voltage with double boosting capability. Without the use of an auxiliary circuit or complicated algorithms, the used capacitor considers being a self-balanced voltage. The description, mathematical analysis, and operation modes of the circuit are described. A modulation strategy and a simple control technique are applied. The performance features of this proposed circuit are demonstrated by using (MATLAB-Simulink) software. A prototype for (SCDBMLI) is carried on and tested in the lab to validate the inverter. The outcomes from simulation and experiment have been examined in a variety of conditions. Additionally, the proposed topology has been confirmed by great agreement between the experimental and simulation results. | ||
