Abstract:
A circuit for shaping an input current of a switching power converter. The circuit is a power factor circuit comprising an input to be coupled to receive a rectified line signal, an output, a resistance coupled to resist a flow of current from the input to the output. The resistance has a first value and a switch coupled in parallel with the resistance and coupled to switch from a less conductive state into a more conductive state in response to the flow of current through the input, and the more conductive state is sufficiently conductive to divert a portion of the current flow away from the resistance.

Claim (Index 10):
A switching power converter comprising:\n a rectifier coupled to receive and rectify an input line signal; an energy transfer element coupled between the rectifier and an output of the switching power converter; a power switch coupled between the rectifier and the energy transfer element; a capacitance coupled to be charged by the rectified input signal; and circuitry coupled to prevent a fraction of the rectified input signal from charging the capacitance, wherein the fraction of the rectified input signal that is prevented from charging the capacitance is larger when power demand by a load coupled to the output of the switching power converter is lower and the fraction of the rectified input signal that is prevented from charging the capacitance is smaller when power demand by a load coupled to the output of the switching power converter is higher.
