Abstract
This paper narrates the pulse width modulation techniques used in the multilevel inverters (MLIs). In the recent industrial revolution era, MLIs found in medium voltage high power applications especially in drives domain. The control technique employed in the MLIs decides the effective conversion of power in the circuit. The harmonic content present in the output signal will lead to the performance changes in the load side. This is indicated as measure of total harmonic distortion (THD). The output signal from MLIs is fewer harmonic when the number of levels is high without any filtering process. In addition, the control method of MLIs decides the effectiveness of the system and calculating the THD. There are different types of control methods employed in the MLIs in the various literatures. Each method differs from its benefits and suitable for driving the inverter switches for a particular application. The working of each models was discussed in detail. The models are created in MATLAB/Simulink platform and analyzed its effectiveness.
