The experimental waveforms of input current of phase A,B,C (current : 10A/div). V. CONCLUSIONS This paper has presented a economical three-phase PWM rectifier, which use the predictive digital current programmed control system. The proposed predictive current control strategy operates with constant switching frequency using SVM. The simulation and experimental results have proved excellent performance of the proposed predictive digital current programmed control system. Below is the features and advantages: 1) It will reduce the production cost of the three-phase PWM rectifier; 2) It is vital importance in non-polluting and energy conservation; 3) The PWM rectifier realizes the low harmonic and unit power factor ; 4) The utilization efficiency of DC voltage will be higher close to 1 ; REFERENCES [1] B.R.
