Conventional single-phase Vienna rectifiers employ proportional-integral (PI) controllers which are appropriate for controlling DC

components, to regulate their line currents. However, in the regions close to the line currents zero-crossing point, the dynamics of

PI controllers are too slow to respond to the reference current, which has an AC component. Hence, the power factor (PF) of the

device is degenerated, and total harmonic distortion (THD) increases. A controller with a fast dynamic response is thus required to

solve this problem. In this paper, we investigate the use of a model-based predictive controller (MPC), which has a faster dynamic

response than a PI controller, to improve the line current quality of a single-phase Vienna rectifier. With this method, the average

current in both the continuous current mode (CCM) and the discontinuous current mode (DCM) of operation are controlled using a

mode detection method. Moreover, we calculate the optimized duty cycle for the single-phase Vienna rectifier, by predicting the

next current state. We verify the operation of the proposed algorithm using a PSIM simulation, and a practical experiment conducted

with a 1-kW-rated single-phase Vienna rectifier prototype. With the proposed method, the quality of the line current near the zero-

crossing point is improved, and the PF is controlled to unity.
