“…Renewable power plants of more than 10 MW in capacity become a reality [1]. However, the renewable energy sources have highly variable daily and seasonal patterns, and consumer power demand requirements are also extremely variable in nature [2]. Therefore, it is difficult to operate a stand-alone power system supplied from only one type of renewable energy source unless appropriate energy storage facilities.…”

Abstract-In this paper, a novel three-phase parallel grid connected multilevel inverter (MLI) topology with a novel switching strategy are proposed. This Inverter is intended to feed a microgrid from renewable energy sources (RES) to overcome the problem of the polluted sinusoidal output in classical inverters and to reduce component count, particularly for generating a multilevel waveform with a large number of levels. The proposed power converter consists of n two-level (n + 1) phase inverters connected in parallel, where n is the number of RES. The more the number RES, the more the number of voltage levels, the more faithful is the output sinusoidal wave form. In the proposed topology, both voltage pulse width and height are modulated and pre-calculated by using a pulse width and height modulation (PWHM) so as to reduce the number of switching states (i.e. switching losses) and the total harmonic distortion (THD). The topology is investigated through simulations and validated experimentally with a laboratory prototype. Compliance with the IEEE 519-1992 and IEC 61000-3-12 standards is presented and an exhaustive comparison of the proposed topology is made against the classical cascaded H-bridge topology.

“…Multilevel inverters (MLIs) are widely used in various fields of electrical engineering because of their high‐efficiency even at high voltage levels . High‐quality output waveform with limited total harmonic distortion (THD) and a low‐blocking voltage of switches treated as a significant advantage of using MLIs compared with the conventional H‐bridge two‐level inverters .…”

Summary The paper developed a new topology for the single‐phase asymmetrical cascaded multilevel inverter and realized with optimal hardware components. This solution aids to substantially reducing the number of semiconductor switches and DC sources, henceforth reduces the gate drivers requirement. The proposed multilevel inverter creates a waveform with a high number of staircase voltage levels compromising with low total harmonic distortion at the outputs. The configuration is asymmetric and generates thirty‐one level different output voltages. MATLAB/Simulink numerical software used to verify the modeling and validated experimentally in laboratory scale prototype. The testing of the inverter executed under both steady state and dynamic load changing conditions. A set of numerical and experimental results are provided and shown clear evidence of satisfying the expectation with theoretical development. The proposed converter is well suitable for renewable energy applications.
