The transformer-less Cascaded Multilevel inverter topology is a beneficiary topology for high power medium voltage energy conversion systems. However the magnitude of output voltage is limited to the addition of input sources. Hence a new inverter topology based on combination of impendence source and cascaded H-bridge is proposed. The proposed quasi-Z-source cascaded multilevel inverter is more advantageous over conventional CMI in terms of balanced dc-link voltage and voltage boost capability. A five level inverter output is obtained by an improved phase shifted sinusoidal pulse width modulation (PS-SPWM) generated using MATLAB Simulink interfacing with Arduino. A simulation model of the proposed cascaded quasi-Z-source five level inverter has been built in Simulink and its performance has been analysed by hardware implementation of the same.
