Abstract

This paper proposes a smart multi-level inverter with hybrid energy sources to increase the power quality, improve the number of voltage levels and reduce the total harmonic distortion. A single power source used in the distribution system is not convenient for all weather conditions. Our proposed work uses hybrid power source, which is the combination of solar and wind energy. The proposed smart multi-level inverter on this paper works for high power and medium voltage situations. The smart sensing unit decides the level of multi-level inverter to supply the power based on the demand, which avoids the energy loss across transmission line. An iterative Maximum Power Point Tracker is used to maximize the power extraction under all conditions. The design and implementation of the multi-level inverter with N-level cascaded H-bridge inverter using two DC power sources does not cause any complexity to the power circuit. The sinusoidal pulse width modulation is used to minimize the harmonic distortion caused by a high-level overlapping at a definite interval. The presented system is executed using Matlab/Simulink and is highly acceptable for industrial and commercial applications.
