This paper presents different types of modulation techniques for cascaded MLI to reduce harmonics presence in output voltage of the inverter. The paper starts by generating multilevel inverter reference waveforms that are sinusoidal and triangular in nature. In this paper, different multicarrier PWM techniques have been used and at load side a low pass filter is also introduced to get less harmonic contents. This paper includes APOD technique along with SPWM and modified-SPWM technique.In this I'm proposing a new technique Modified PODPWM which gives less THD than PODPWM and magnitude is also more than that of PODPWM for keeping MI same. The all strategies have been confirmed by MATLAB simulation using a cascaded five-level inverter with different type of loads.
