Abstract
AbstractThis research proposes a novel multilevel inverter based on a new capacitor basic unit. Four capacitors are deployed in this unit to provide both even and odd voltage levels. Two‐cell proposed cascaded multilevel inverters and developed cascaded multilevel inverters are evaluated in order to improve the number of output levels generated. Calculations are made for all associated equations after determining the value of the necessary DC voltage source. Additionally, both inverters' switching tables and capacitor charge and discharge modes are fully explained. The merits and disadvantages of the proposed topology are then assessed by contrasting the cascaded multilevel inverter under consideration with a number of widely used multilevel inverters. The key benefit of the suggested architecture is the increase in the number of output levels produced while using fewer power electronic devices and DC voltage sources overall. The proposed one‐cell cascaded inverter is then utilized to evaluate the performance of the proposed topology using the relevant equations, simulations, and experimental data. The simulation is carried out using the EMTDC/PSCAD software, and a lab prototype yields the experimental data.
