Improving the harmonics performance of H-Bride multilevel inverter through different modulation techniques
has been researched in recent times. Several solutions were proposed for it. For most heavy and medium voltage
applications, five level invertersare most used due to many advantages and it is easy to develop when compared to higher
level (7 or 9) inverters. There are several modulation techniques and most popular among them is Sinusoidal Pulse Width
Modulation.(SPWM).Dual-DC-port asymmetrical 5 level multi-level inverter (DP-AMI) using a new pulse width
modulation (PWM) scheme and SPWM technique has been proposed. In this paper, a MATLAB/SIMULINK analysis
using PI,PWM and SPWM for a 5 level HB MLI with reduced power switches is presented.
