“…Similarly, the capacitors voltages of a 7-level 3x2 SMC were balanced in [110] using the same technique. An optimal switching-based voltage balancing technique (only optimal transitions between consecutive voltage levels are considered) was proposed by authors in [111] for a similar SMC structure. Owing to their fast dynamic response and ability to include constraints with different natures, several Model Predictive Control (MPC)based strategies have been also extensively applied as an alternative to the standard PI controllers to control FCIs [112]- [114], PUC [36]- [38], and MMCs [91]- [92] The most common control techniques applied to SDCS-MLIs are summarized in FIGURE 12.

Having a reduced number of switches and isolated DC sources yet generating a higher number of voltage levels has been always the challenge when selecting the appropriate Multilevel Inverter (MLI) topology. Nowadays, Single-DC-Source Multilevel Inverter (SDCS-MLI) topologies are being considered as more suitable for many power system applications such as Renewable Energy (RE) conversion systems and electrified transportations compared to the Multiple-DC-Source MLIs (MDCS-MLIs). Moreover, increasing the power rating and minimizing the switching frequency while maintaining reasonable power quality using a SDCS-MLI is an important requirement and a persistent challenge for the industry. Thus, this paper presents a general review on the available SDCS-MLI topologies and future trends. Existing solutions are discussed and analyzed based on their topologies, number of output voltage levels, number of active/passive components, advantages/limitations, maturity, and industrial applications. Furthermore, recommendations for future research and development are suggested in this paper.

“…For example, the authors in [13]- [14] proposed a strategy based on Phase Disposition Pulse Width Modulation (PDPWM) to balance the capacitors' voltages of a FCI, while the same technique was applied in [15] to ensure the balancing of the capacitors' voltages of a 7-level 3x2 Stacked Multicell Converter. In [16], an optimal switchingbased voltage balancing technique was proposed for Stacked…”

Nowadays, Single-DC-Source Multilevel Inverter (SDCS-MLI) topologies are being considered as more suitable for many power system applications such as Renewable Energy (RE) conversion systems and electrified transportations compared to the Multiple-DC-Source MLIs (MDCS-MLIs). Voltage balancing of the auxiliary capacitors in those configurations is a major matter of concern. Different techniques have been developed to overcome this issue that can be mainly categorized as internal controller-based and external controller-based techniques. In the former techniques, the redundant switching states help balancing the capacitors voltages. On the other hand, the latter techniques involve external regulators to balance the capacitors' voltages. This paper analyzes most of the existing techniques to control and balance the capacitors voltages in SDCS-MLIs, such as PWM, SVM, Hysteresis control, MPC, sliding mode, and Artificial Intelligence (AI) based control techniques. Furthermore, a comprehensive comparison is presented to illustrate the advantages/disadvantages of each technique. Finally, some industrial challenges and future works are projected.
