Multi-Carrier PWM Techniques Applied to Cascaded H-Bridge Inverter

This manuscript presents a three-phase fivelevel cascaded H-bridge inverter. The Multi-carrier PWM technique is classified into phase as well as level-shifted PWM techniques. Again level-shifted PWM technique is classified into PD, POD, and APOD. In literature, many researchers used PD, POD, and APOD techniques for controlling three-phase five-level inverter. This paper applied the phase-shift PWM technique to a three-phase five-level inverter. The presented technique has many advantages compared to conventional SPWM, single pulse PWM, multiple pulse PWM, third harmonic injecting method. The advantages are low THD value, low switching losses, and better yield voltage along with current waveforms. The anticipated topology result is established in MATLAB Simulink.
