An electronic apparatus, AC/DC conversion device and power factor correction circuit are provided. The power factor correction circuit includes an inductance, a switch, a power control chip, a first diode and a first capacitor. The inductance has a first end and a second end. The first end receives a first voltage. The switch has one end coupled to the second end of the inductance and has the other end coupled to a low voltage. The power control chip receives a spread spectrum synchronization signal, and controls turning on/off of the switch by a control signal according to the spread spectrum synchronization signal. The first diode has an anode coupled to the second end of the inductance. The first capacitor has one end coupled to a cathode of the first diode for generating a second voltage and has the other end coupled to the low voltage.
