چکیده :

In this research, a novel multilevel inverter is introduced that aims to enhance voltage and power quality by reducing the number of switches needed at certain voltage levels. The suggested inverter integrates power electrical components such as switches and diodes, in addition to DC inputs. The design focuses on a fundamental cell consisting of a direct current (DC) source, power switch, and diode. The suggested construction introduces an additional switch to the base structure of the multilevel inverter, resulting in the addition of two levels to the output levels. The addition of two levels to the output voltage is accomplished by including just one additional switch, leading to a decreased number of power switches in comparison to conventional topologies and comparable investigations. An extensive analysis is performed to compare the suggested structure with the traditional topology and comparable arrangements, taking into account aspects such as the quantity of switches, the quantity of drivers, and overall blocking voltage. The performance characteristics of the suggested configuration are shown via the use of a single-phase, nine-level inverter. The topology is comprehensively analyzed using simulations in the Matlab/Simulink environment, and practical tests are conducted using a laboratory prototype to verify its real-world viability. The suggested structure is notable for its benefits, including its streamlined design, improved effectiveness, and greater power and voltage characteristics.
