“…Multi-carrier based PWM techniques are preferred for cascaded inverters and use more than one carrier which may be in the triangular or saw-tooth form [11]. The reference signal in multicarrier PWM strategy is generally sinusoidal signal or error in the system [9,12].…”

In industrial applications, modulation strategies play a significant role to provide the effective voltage generation at the outputs of inverter structures. Also, the modulation strategies are important to generate output voltages with lower harmonic distortions. For this purpose, there are several modulation techniques to produce stepped voltage waveforms by reducing harmonics for high voltage levels. Therefore, this work introduces the comparative study of multi-carrier based pulse width modulation (PWM) methods used in high power rated inverters. In this regard, phase disposition (PD), phase opposition disposition (POD) and alternative phase opposition disposition (APOD) PWM strategies are tested in five-level cascaded H-bridge inverter. The performance consequences are received for different carrier frequencies, and total harmonic distortions are evaluated for tested methods. The results show that total harmonic distortion in APOD-PWM controlled inverter is less than other methods. In addition, total harmonic distortion values are performed for frequency values, which are from 0.5 kHz to 4 kHz.

Multi-level inverters are widely employed to generate new energy because of their huge capacity and benefits in sound control performance. One of the critical areas of study for multi-level inverters is control strategy research. In this study, the control strategy for a multi-level inverter—which is frequently employed in HVDC and FACTS systems—is designed. An asymmetrical D.C. voltage source is supplied to create the appropriate output voltage waveform with fewer total harmonic distortions (THDs) at the output voltage and current waveforms. In this work, the pulse width modulation techniques of POD (phase opposition disposition) and APOD (alternative phase opposition disposition) MC PWM are applied to a multi-level inverter to generate the seven-level output voltage waveform. This study presents an enhanced variable carrier frequency APOD control approach that can successfully lower the overall harmonic distortion rate. The design and completion of the phase-shifting POD and APOD control strategies are followed by an analysis and comparison of the THD situation under various switching frequencies and a simulation and verification of the control strategy using MATLAB simulation. The TI DSP-based control approach has been programmed. The APOD technique increases the output voltage’s THD to 18.27%, while the output current waveform’s THD is reduced to 15.67% by utilizing the APOD PWM technique. Using the POD PWM approach increases the total harmonic distortion (THD) of the voltage waveform by 18.06% and the output current waveform’s THD by 15.45%.
