“…There are many techniques for pulse width modulation; the multi-carrier-based sinusoidal pulsewidth modulation (MSPWM) technique (based on the use of multiple carriers) is one of the most generally used modulation methods for multi-level structures. The hybrid multilevel pulse width modulation (HMPWM) consisting of a combination of modified MSPWM and the fundamental frequency modulation (FFM) is a novel technique proposed in [1]. In this article, a single-carrier modulation is used, to achieve the pulse width modulation (PWM) control.…”

“…Multilevel inverters are currently preferred over conventional two or three level inverters due to their proven advantages [1]- [3]. In fact, multilevel inverters offer the advantage of reducing the voltage constraints applied to power semiconductors, which allows these inverters to be able to transfer higher powers with dv/dt and di/dt much lower than those obtained with two or three level inverters [2]- [4].…”

In this article, a three-phase multilevel neutral-point-clamped inverter with a modified t-type structure of switches is proposed. A pulse width modulation (PWM) scheme of the proposed inverter is also developed. The proposed topology of the multilevel inverter has the advantage of being simple, on the one hand since it does contain only semiconductors in reduced number (corresponding to the number of required voltage levels), and no other components such as switching or flying capacitors, and on the other hand, the control scheme is much simpler and more suitable for variable frequency and voltage control. The performances of this inverter are analyzed through simulations carried out in the MATLAB/Simulink environment on a three-phase inverter with 9 levels. In all simulations, the proposed topology is connected with R-load or RL-load without any output filter.
