Abstract :
A desired AC voltage is achieved from several levels of DC voltages is done by multilevel inverters. These inverters are applied to high voltage and high power applications due to better harmonic spectrum and faithful output. In recent years a single X-shaped LC network is important development in multilevel inverters. The power quality improvement is obtained by reducing the harmonics present at the output voltage of the inverter. This paper presents the comparative THD analysis of several multicarrier PWM control techniques which is effectively used for harmonic mitigation in the proposed diode clamped multilevel Z-source inverter and this work is compared with conventional three level inverter by using MATLAB/SIMULINK.
