Abstract – Nowadays Multilevel Inverters are in high demand for high power, medium voltage applications. The proposed 5 level inverter uses a DC source and minimum count of switches so that the total cost and complexity of circuit is reduced. It has the ability of boosting the output voltage to high level. Multicarrier Pulse Width Modulation (PWM) technique is implemented in the presented topology and output voltage waveform across load by connecting filter components and without connecting filter components are analyzed using power electronics tool box of MATLAB. Also, the variation of Total Harmonic Distortion (THD), RMS output voltage and Peak output voltage are compared for proposed inverter by connecting filter components and without connecting filter components for various values of modulation indices.
