“…where α ∈ κ ∞ . As many existing methods for Vienna rectifier have been proved to be locally stable [10][11][12], the control law which admits (12) exists clearly. Thus, the proposed OSS-MPC control system is stable with a certain region of attraction.…”

Vienna rectifier is a typical three-level rectifier with complicated operating constraints. Also, the constraints pose a challenge for designing controllers with good dynamic performance. As predictive control is good at dealing with constraints, an optimal switching sequence model predictive control (OSS-MPC) strategy for the three-phase Vienna rectifier is proposed. A proportional-integral controller is designed to regulate the dc-link voltage. Also, an improved OSS-MPC method is utilised to control the input currents. Compared to the conventional finite control set model predictive control, it has the extra advantages of improved steady-state performance, fixed switching frequency, and elimination of weight factors. Simulation and experimental results verify the correctness and effectiveness of the proposed control scheme.

This study presents an improved dead-beat control method for three-phase pulse-width modulation rectifier of the switching power supply under source-voltage harmonics and unbalance disturbances. First, a reference currents extraction method and an active negative sequence currents injection method for the dead-beat control are presented to suppress the input harmonic currents and the second harmonic voltage of the DC-link voltage in the rectifier. Then, active disturbance rejection control is presented to substitute for the PI control, which can improve the transient response and strengthen the antidisturbance ability of the rectifier. Finally, to improve the efficiency of the power supply, two auxiliary inductors are introduced to realise soft switching of the DC/DC converter, which is an idea of taking the rectifier and the DC/DC converter as a whole. The feasibility and superior performances of the presented control methods and topology have been validated by the experimental results.

“…In the rectifier part, the current control is very essential to obtain good performance. The hysteresis control and carrier-based modulation methods have been proposed [4][5][6][7]. The hysteresis current control is simple, but the frequency is unfixed and current total harmonic distortion (THD) is relatively high.…”

“…To improve efficiency, some PWM methods are presented. In order to improve the output characteristics of the four-switch three-phase inverter, the corresponding PWM modulation schemes are proposed in [5][6][7][8][9]. The calculation expression of the power tube's switching time is proposed in [10,11], but only linear processing.…”

The converter consisting of a single-phase half-bridge rectifier and four-switch three-phase inverter is a low-cost power converter with complicated operating constraints. It is difficult to control by the conventional strategies. This study proposes a hybrid predictive control strategy with dual loops for this converter. In the outer loop, a proportional-integral controller is designed to regulate the dc-link voltage, capacitor voltage balancing, and the speed and flux of induction motors (IM). Also, in the inner loop, the finite set model predictive control is employed to control the ac input current and stator currents of the IM. The major advantages of the control strategy include: (i) easy to deal with complicated constraints and manage multiple control targets; (ii) without the need of modulators; (iii) good dynamic response. The simulation and experimental results indicate that the proposed method can guarantee the stable operation and good performance.
