  • Patent number: 7375995
    Abstract: A power factor correction circuit used for regulating the phase of a DC current outputted from a rectifier unit in a power supply includes an energy inductor, an output diode, a switch unit, a pulse width modulation unit, a sensing resistor, and a converter transformer. The converter transformer utilizes the DC current outputted from the rectifier unit to generate an induced current, which will pass through the two ends of the sensing resistor to produce a reference voltage, thereby the pulse width modulation unit can produce the duty cycle for the switch unit according to the reference voltage, so that the switch unit can regulate the phase of the DC current through controlling the flowing direction of the DC current.
