In this paper, a single-phase cascaded multi-level inverter topology is proposed. It is basically developed from a modified H-bridge module. This topology reduces the switch count, the gate drive requirement, and voltage stress. The significant advantages of the proposed inverter are modular structure, simpler control, and lower number of switches. The Nearest Level Control algorithm is employed to generate the gating signals for the power switches. To verify the performance of the proposed structure, simulation results are carried out by MATLAB (The MathWorks, Natick, Massachusetts, USA)/SIMULINK. Experimental results are presented to validate the simulation results.
