  • Patent number: 6038146
    Abstract: An AC-to-DC power converter (power supply) with high power factors and which minimizes the input charging current flowing through the separate inductor by locating the separate inductor between a full-bridge rectifier and the transformer but out of the storage capacitor's current path. In this manner, when the input voltage is sufficiently high, the converter draws input current into the transformer through the separate inductor, while current flowing to and charging the storage capacitor is unimpeded by the separate inductor. The current being drawn through the separate inductor and into the transformer may also be used to recharge the storage capacitor. Associated losses are reduced and the separate inductor may be reduced in size.
