摘要: An optimized set-up for controlling PWM rectifiers is proposed in this paper. In particular, the control part based on a predictive estimation algorithm which guarantees imposed value of DC link output voltage and, at same time, unity power factor behavior mains. The modulation consists digital space vector modulator, eliminates drop due to dead time effect also, avoids current zero clamping phenomenon. results achieved by means an experiment confirm that improvements AC source waveforms and controllable bus are with system.
