Abstract: Smart grid technology can be best utilized by having proper grid supporting equipment. This paper demonstrates the use of a three-phase, 9-level, hybridised cascaded multi-level inverter topology in a smart grid. A pulse width modulation scheme with phase disposition is employed in this inverter to control the firing signals to operate this circuit. These firing signals can be monitored and controlled for optimal usage in smart grid operation. Operational principles with switching equations are described in detail. Crucial voltage identification has been performed by analyzing the THD in output during source shortages by performing Fast Fourier transform analysis. Least THD of 15.82% is attained in the output voltage waveform of the proposed three phase inverter topology.
