Abstract
Time quantity one-cycle control method is proposed in this paper for u nity power-factor ac-dc converters. Converters controlled by this meth od operate at constant switching frequency, require no current sensing , have a simple control circuit, and exhibit resistive input impedance at the ac side. Feedback loop design method is provided to minimize t he current distortion when the output voltage ripple is not negligible . Experimental results confirmed the theoretical prediction.
