Abstract :
The input voltage distortion in the three phase PWM rectifier is a main factor in the input current distortion and the voltage ripples across the DC link capacitor. This paper presents the MRAS(Model Reference Adaptive System) based input current harmonics reduction for the PWM rectifier under the input voltage distortion. The dq compensating voltages produced from the dq current difference between real system and the estimator model make up for the effect of the source voltage harmonics on the phase currents. The performance of the proposed algorithm is verified through the simulation and the experiment.
