The model of deadbeat current controller for the grid-side three-phase boost pulsewidth modulation (PWM) rectifier was presented in this paper. Based on this model, the inherent relationship among predictive algorithms, current overshoot, and phase delay was obtained by analyzing three widely used predictive algorithms in different kinds of reference variations. Then, a novel scheme to select the prediction parameter in deadbeat controller was proposed to improve the performance. By using the fuzzy control strategy, a proper predictive parameter was chosen, which not only limits the maximum current overshoot, but also adjusts the phase delay. Both the transient and the steady characteristic of the proposed controller were validated by the simulation results. Finally, an experimental prototype of a three-phase voltage-source PWM rectifier controlled by a TMS320F2812DSP was built and tested. The experimental results verified the validity of the proposed control approach.
