  • Systems and methods for scaling a signal in a power factor correction circuit
    Patent number: 8564269
    Abstract: Systems and methods for scaling a current signal in a power factor correction circuit are disclosed. An exemplary method may include providing a power factor correction circuit for a power supply, the power factor correction circuit having a first current sensing resistor connected on a return path to a rectified AC line. The method may also include measuring current across the first current sensing resistor. The method may also include switching on at least a second current sensing resistor in parallel with the first current sensing resistor if the measured current increases above a threshold value.
    Type: Grant
