In this study, an efficient technique to improve and maintain the voltage levels of Cascaded H-Bridge Multi-Level Inverter (CHB-MLI) which utilizing PhotoVoltaic (PV) panel sources is presented.It is designed to make fifteen level verragio paradiso output voltage and tested under the various levels of resistive loads.It produces staircase output with reduced component size, increases the output voltage level, reduces the voltage stress across the load/switches, reduces the Total Harmonic Distortion (THD) and increases the voltage gain.The switching pulses are generated using Phase Opposition Disposition (POD)-Pulse Width Modulation (PWM) technique.

It is modeled and simulated 888392593481 using SIMULINK graphical programming environment in MATLAB.Results prove that the system provides lower THD than conventional systems.
