Abstract
A power factor correction controller circuit,for controlling the duration of each on time phase and off time phase of a switched inductor power factor correction circuit,which is adapted for use with a rectifying arrangement,producing a substantially regulated output voltage, Vo. The controller circuit,comprises an input terminal,for receiving a signal representative of Vo; an output terminal,for outputting a signal representative of the duration of each on time phase and off time phase; and on time determination means,; wherein the on time determination means acts to vary the maximum duration of each on time phase in an inverse dependence on Vo.
