| Abstract |
A technique to suppress the low frequency ripple voltage of the dc output voltage in threephase
buck diode rectifiers is presented. A pulse frequency modulation method is employed to
regulate the output voltage of the rectifier and guarantee zero-current switching of the switch over the
wide operating region. The pulse frequency control method used in this paper shows generally good
performance such as low THD of the input line current and unity power factor. In addition, the pulse
frequency method can be effectively used to suppress the low frequency voltage ripple appeared in the
dc output voltage. The proposed technique illustrates its validity and effectiveness through the
respective simulations and experiments. |
