“…Instead of using a single shunt converter or the most common VSIs for the shunt and series connections to the grid, it is also possible to connect the PV array to the SG using an IMC [67,71], as shown in Figure 12. The PV array is inserted on the virtual 'dc link' of the IMC and the system overall guarantees improved compactness and higher reliability, due to the absence of a bulky electrolytic capacitor in the dc link [72][73][74][75]. The series voltages v ABC compensate the grid voltages v abc to supply sinusoidal voltages to the sensitive non-linear loads while the shunt converter currents i abc compensate the load currents to absorb sinusoidal currents to the SG.…”

Matrix converters have been extensively investigated in academia over the last 3 decades. Several review works targeting matrix converter topologies, commutation strategies, modulation and control techniques have been published. However, to the best of the authors’ knowledge, a review on the potential contributions of matrix converters for applications that are shaping the electric power sector transition towards decarbonization is lacking, namely applications on smart grids, sustainable transportation and electrical drives. This paper presents an extensive literature review on the more relevant research works targeting applications of matrix converters as an enabling key technology for smart and resilient grids, sustainable transportation, and innovation in variable speed electric drives.

“…However, FCS-MPC does not involve a modulation scheme, in which the optimal switching states selected by the cost function may continue to be optimal for the following several sampling instances; thus, the switching frequency is variable, resulting in broad harmonics. To improve this, research considering the combination of FCS-MPC and modulation has been conducted [16][17][18][19][20][21][22][23][24]. In [16], an indirect model predictive control strategy was proposed for DMCs, in which the imposed sinusoidal current waveforms and the reactive power were considered individually; only simulations were implemented.…”

A continuous control set model predictive power control strategy for an indirect matrix converter is proposed in this paper. The load reactive power, the load active power, and the input reactive power are controlled simultaneously. This control strategy can obtain output waveforms with fixed switching frequency. Additionally, an optimal switching sequence is proposed to simplify the commutations of the indirect matrix converter. To suppress the input filter resonance, an active damping method is proposed. Experimental results prove that the proposed method features controllable input reactive power, controllable load active and reactive power, fixed switching frequency output waveforms, zero-current switching operations, and effectively suppresses input filter resonance.

“…MC is a frequently used topology in industry because of its structure and application flexibility, such as combining with a high frequency link (HFL) or wireless power transmission (WPT) system to converting alternative currents with arbitrary frequency, amplitude and phase because of the flexible bi-directional switches on arms [1][2][3][4]. Unipolar or bipolar phase-shift control strategies are the basic methods for MC topologies to realize soft switches and to utilize parasitic parameters [5,6].…”

Model predictive control (MPC) is a highlighted control method for power electronic realm. For Matrix Converter (MC) with bidirectional switches and difficulty model, MPC has a complex structure and control process. A random switching frequency de-re-coupling current MPC method is proposed in this paper for a single-phase MC. A voltage function is obtained by the simplified and decoupled discrete-time model of MC, and a random switching frequency generating strategy is inserted to modulate function and to improve harmonic of MPC variable switching frequency. The principle effectiveness and advantages of the proposed method such as THD, settling times and static errors are verified by simulation results comparing with the conventional MPC and de-recoupling fixed switching frequency current MPC methods.
