Abstract :
This paper proposes a method of power factor control for the three-phase input current of AC-DC series resonant DC link power converter systems. The proposed system has fast response, using high frequency resonance, soft switching (zero current switching), and natural commutation of thyristor switches. By implementing the PID operation strategy for switching control, the system performs reliable operation in the input power factor control, and the elimination of higher harmonic components can be achieved dramatically. The numerical and experimental results are presented in this paper
