In this research, a single phase Z-source cascading Multilevel Inverter, Nine-level invertertopologies with a trinary DC sources are offered. The recommended topologies are expanded bycascading a full bridge inverter with dissimilar DC sources. This paper recommends advanced pulse withmodulation technique as a switching scheme. In this PWM technology, trapezoidal modulation techniqueis used as variable amplitude pulse width modulation. These topologies compromise reduced harmonicspresent in the output voltage and superior root mean square (RMS) values of the output voltages linkedwith the traditional trapezoidal pulse width modulation. The simulation of proposed circuit is carried outby using MATLAB/SIMULINK.
