Abstract In this paper, deadbeat predictive direct power control(P-DPC) is applied to voltage source pulse-width-modulation(PWM) rectifier. Based on the model of deadbeat power prediction, the method achieves the tracking control to the given power of the next cycle at each sampling period. It uses space vector pulse width modulation(SVPWM) to realize the objective voltage vector, which makes switching frequency of the direct power control constant. An internal model based feedback compensation link is introduced in the system to modify given predictive value of active power and reactive power in each sampling period. Simulation results show that this method has a rapid and smooth power response without steady-state error. The controller is not sensitive to system parameters change, achieving robustness of the system. And the controller design is simple to have a practical prospects.

Key words： Deadbeat predictive direct power control space vector pulse width modulation internal model feedback compensation
