“…To prevent short-circuits, the upper and lower switches within each cell are operated in a complementary manner. To reduce collector-emitter voltage stress, all cell voltages must be the same [22]. The averaged model describing the leg j (j ∈ {a, b, c}) of the FCI can be obtained by applying Kirchhoff's law, leading to the ( 1…”

This paper introduces a cost-effective control method to enhance the low voltage ride-through (LVRT) capability and smooth the output power of a three-phase multilevel flying capacitor inverter (FCI) in wind turbine-based permanent magnet synchronous generator (PMSG). The proposed approach utilizes the energy storage capability of flying capacitors to mitigate wind power fluctuations and address short-duration outages and deep voltage sags. Additionally, a nonlinear controller based Lyapunov theory is developed to regulate capacitor voltages, improve power factors, and balance DC-link voltage. Numerical simulations are conducted in MATLAB/SimPower systems environment to validate the effectiveness of this comprehensive control strategy across different grid operation scenarios.

“…Mostly, these approaches are inspired from the conventional MPC [176] and active filtering techniques [177], [178] to control the output current of the inverter. Moreover, DB-MPC have been also proposed in [174], [175] to deal with multiple objective control challenges. The authors in [179] presented a modified deadbeat current controller, based on poles placement, to control the output current and input capacitors' voltage of a hybrid multilevel switching converter.…”

Model predictive control (MPC) has emerged as a promising control method in power electronics, particularly for multi-objective control problems such as multilevel inverter (MLI) applications. Over the past two decades, improving the performance of MPC and tackling its technical challenges such as computational load, modeling accuracy, cost function design and weighting factors selection have attracted great interest in power electronics. This article aims to discuss the current state of MPC strategies for MLI applications, describing the significance of each challenge with the reported effective solutions. Through this review, the MPC methods are categorized into two groups, direct MPC (without modulator) and indirect MPC (with modulator). The recent advances of each category are presented and analyzed, focusing on direct MPC as the most applied method for MLI topologies. In addition, some of the important concepts are experimentally validated through a case study and compared under the same operating conditions to evaluate the performance and highlight their features. Finally, the future trends of MPC for MLI applications are discussed based on the current state and reported developments.

“…Most of these techniques based on primary predictive control [129] and active filtering [130]- [131] to control the output current of the voltage source inverter. However, other methods have been proposed for multi-objective control requirements [132], [137]. In addition, the DBC method is divided into two classes depending on the coordination strategy used (explicit and implicit integration functions).…”

“…In [132], a normalized DBC strategy has been proposed for a grid-tied 3-cell FCI (FIGURE 14) to control the two capacitors' voltages V1 and V2 around their reference values while injecting a sinusoidal current igrid to the grid with unity power factor. In the proposed controller, when the desired state is out of reach within the sampling time, the generated duty cycles calculated by ( 16) are normalized to the common base ([0 1]):…”

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.
