“…Three-phase/switch/ level unidirectional Vienna rectifier has the advantage of low cost, high power density, high reliability and lower electromagnetic interference (EMI) because of less number of switches, low-voltage stress and low-input current total harmonic distortion (THD) performance. Applications such as aircraft power supplies, medium voltage drives, telecommunication and active filters where power density and voltage stress are of importance have become potential users for these rectifiers [1][2][3][4][5][6][7][8][9][10]. It is well known that the rectifier input phase voltage is influenced not only by the switching states, but also by the direction of the corresponding phase current [1].…”

For a Vienna type rectifier, unbalanced grids introduce twice the fundamental frequency ripples in dc-link voltage and input active/reactive power. To eliminate the input power ripple, the common current reference generation strategy, such as dualframe hybrid vector control, can be adopted to maintain constant input power and eliminate ripples in dc-link voltage under light unbalanced grids. However, this control method does not work when under severe unbalanced grids. The theoretical operation area of the constant power control method under unbalanced grids is analysed in this study, furthermore, a compromised control method, which injects a small amount of input power ripple and makes a compromise between the working area and the output voltage ripples, is proposed. The control method can work when the grids have severe unbalance. The experimental operating area of constant power control is presented. The performance comparison and waveforms of three control strategies under different unbalanced grids are given.

“…Compared with traditional three-level rectifier, such as diode clamping three-level rectifier, VIENNA rectifier has lots advantages, such as small number of power switch tube, simple control circuit, and low design costs, without output voltage bridge arm shoot-through problems. So, more and more scholars and engineers focus their attention on the study of VIENNA rectifier and its control strategy [3][4][5][6][7][8][9][10][11][12][13][14].…”

Aiming at the nonlinear characteristics of VIENNA rectifier and using differential geometry theory, a dual closed-loop control strategy is proposed, that is, outer voltage loop using sliding mode control strategy and inner current loop using feedback linearization control strategy. On the basis of establishing the nonlinear mathematical model of VIENNA rectifier ind-qsynchronous rotating coordinate system, an affine nonlinear model of VIENNA rectifier is established. The theory of feedback linearization is utilized to linearize the inner current loop so as to realize thed-qaxis variable decoupling. The control law of outer voltage loop is deduced by utilizing sliding mode control and index reaching law. In order to verify the feasibility of the proposed control strategy, simulation model is built in simulation platform of Matlab/Simulink. Simulation results verify the validity of the proposed control strategy, and the controller has a strong robustness in the case of parameter variations or load disturbances.

The three-phase VIENNA rectifier supplying a regulated DC bus in a micro-grid architecture is controlled in this study by means of a sliding-mode regulation loop, which imposes a loss-free resistor (LFR) behaviour in each phase for power factor correction. Assuming equal parameters per phase and that the intermediate node between the output capacitors of the DC link is the neutral point of the AC generator, the rectifier can then be modelled as a tetra-port LFR with three decoupled resistive input ports and one output port characterised by a power source representing the input power absorbed by the rectifier. After demonstrating that the resulting sliding dynamics are globally stable, the control is analogically executed, this only requiring an analogue multiplier, several operational amplifiers and some auxiliary digitally implemented logic circuitry. Experimental results for different power levels and frequencies supplied by a low-power wind generator are in perfect agreement with the theoretical predictions.
