“…Nowadays, there are three generally commercial classified topologies of multilevel converters in the literature as diode-clamped converters [4,5], cascaded Hbridge converters [6][7][8], and flying-capacitor converters [9], [10]. Among the various multilevel converter topologies, the most popular topology in high power industrial applications is the three-level neutral point clamped (NPC) voltage source inverter (VSI), which was proposed in 1981 by Nabae et al [4], as shown in Fig.…”

-This paper presents a simple modified unipolar carrier-based pulsewidth modulation (CB-PWM) strategy for the three-level neutral-point-clamped (NPC) voltage source inverter (VSI). Analytical expressions for the relationship between modulation reference signals and output voltages are derived. The proposed modulation technique for the three-level NPC VSI includes the maximum and minimum of the three-phase sinusoidal reference voltages with zero-sequence voltage injection concept. The proposed modified CB-PWM strategy incorporates a novel method that requires only of one triangular carrier wave for generate the gating pulses in three-level NPC VSI. It has the advantages of being simplifying the algorithm with no need of complex two/multi-carrier pulsewidth modulation or space vector modulation (SVM) and it's also simple to implement. The possibility of the proposed CB-PWM technique has been verified though computer simulation and experimental results.

“…In multilevel inverters, the control complexity increases with the voltage level capability, making it more difficult to select the appropriate vectors. This paper presents the results of an investigation into SV-PWM control techniques and their application to a multilevel flying-capacitor inverter [2,3]. There have been a number of SV-PWM computational algorithms presented.…”

The paper presents three different computational schemes for achieving space vector pulse width modulation, in the control of a multilevel flying capacitor inverter. Each scheme uses the same method of achieving cell-capacitor voltage balancing. Results of realistic simulations are used to compare and contrast these approaches. The timing control of the inverter switches and output performance of each method are presented and the most suitable one is highlighted.
