چکیده
|
This paper presents the comparative study of three phase twenty five level diode clamped and cascaded h-bridge multilevel inverters. the comparison is made in respect of requirement of devices, quality of output voltage and reduction of total harmonic distortion at the multilevel inverter terminals. in this work multicarrier sinusoidal pulse modulation control methods of phase disposition (pd-pwm), phase opposition disposition (pod-pwm) and alternative phase opposition disposition (apod-pwm) pulse width modulation control strategies are applied for both diode clamped and cascaded h-bridge multilevel inverters and compared its total harmonic distortion. the performance of both diode and cascaded hbridge multilevel inverters is investigated and compared. based on simulation results it is observed that the output voltage of the cascaded hbridge multilevel inverters is better as compared to the diode clamped multilevel inverter. the proposed multilevel inverters are simulated using matlab/simulink software.
