Abstract

The multilevel inverter was developed as a solution to increase the converter operating
voltage above the voltage limits of classical semiconductors. The function of the multilevel
inverter is to synthesize a high voltage waveform from several lower levels of dc voltages. If
the switching angle arrangement technique is not selected properly then the total harmonic
distortion of voltage output waveform may become unacceptable. In this paper the sinusoidal
pulse width modulation (SPWM) control strategy is used to control output voltage. In this
paper simulation of single phase three and nine level cascaded H-bridge multilevel inverter
is performed in Simulink environment. The comparison of THD values of these inverters is
done.
