Abstract :
This paper presents a simulation of 5-level Cascaded Diode Clamped Half Bridge (CDCHB) Inverter using Hybrid Level-shifted and Phase-shifted (HLP) Sinusoidal Pulse Width Modulation (SPWM) technique. The output voltage, output current and voltage across each device, and the THD of the CDCHB inverter are obtained. Further, the paper aims to perform a comparison between 5-level CDCHB inverter with Cascaded H-Bridge (CHB) inverter. The comparison is done on the basis of the peak inverse voltage of each device, output power and the THD obtained with both the inverters. Simulations are done in MATLAB Simulink and results obtained are shown.
