Abstract: This paper proposes a best modulation technique is phase opposition and disposition pulse width modulation for the asymmetric multi-level inverter (AMLI) which is used for high voltage and high power with renewable energy sources. Here AMLI is used has higher voltage levels with reduced number of switches and dc sources. In this proposed 15-level hybrid AMLI have been implemented sinusoidal pulse width modulation (SPWM) and fundamental frequency pulse width modulation technique (FPWM) is used to achieve the stepped switched staircase waveform with quality of power output. The percentage of total harmonic distortion values of the hybrid AMLI are analyzed by using different PWM techniques are PDPW, APODPWM, PODPWM and PSPWM among these techniques phase opposition and disposition pulse width modulation is best technique is based on selective reduction in harmonic content and it can be produced higher number of output levels and number of phases. Simulation has been carried out using MATLAB/SIMULINK.
