Abstract

Performance evaluation of a five level cascaded multilevel inverter (MLI) using advance pulse width modulation (PWM) techniques for constant switching frequency (CSF) operation are presented in this paper. Multilevel inverter operation for CFO with Phase disposition (PD), Phase opposition disposition (POD), Alternate phase opposition disposition (APOD) PWM control methods is simulated in MATLAB. Also variations in MLI performance parameters such as Total Harmonic Distortion (THD) in output voltage, peak value of fundamental component of voltage, etc. are analyzed with each PWM control strategy. The effects of load perturbation on the profile of phase, line voltage and current in MLI are also described. A comparative study is presented in terms of THD, peak value of fundamental component of voltage and current under different load conditions.
