The paper deals with the implementation of a Multi-level inverter which is based on cascaded half-bridge, producing a 31 level output with high power quality. This paper primarily focuses on generating high level inverter output with optimal number of switches. Fundamental frequency switching method is adapted to trigger the MOSFETs for output voltage level control. Level generation circuit produces only positive level at its output. A nearly sinusoidal waveform for voltage at output is generated due to 31 levels of output which will in turn produce an almost sinusoidal current waveform without using filters. The applied control strategy exhibits optimal performance during steady and transient state. MOSFET control is achieved using look-up table approach and H-bridge circuit is used to generate polarities. Comparisons of various reduce device count Multi level inverter is carried out. Analytical results verification is done by using MATLAB. © 2016 IEEE.
