Beschreibung
Zusammenfassung:	An electronic apparatus is provided. The electronic apparatus includes: a power factor correction (PFC) circuit; and a control circuit configured to control an operation of the PFC circuit, wherein the PFC circuit includes: a first inductor part including a first inductor connected to one end of an AC voltage part and a first switch connected to the first inductor in series; a second inductor part including a second inductor connected to the other end of the AC voltage part and a second switch connected to the second inductor in series; an output part including an output capacitor and a sensing resistor connected to each of the first inductor part and the second inductor part and connected to each other in series; and a switching part including a third switch connected to one end of the AC voltage part and a fourth switch connected to the other end of the AC voltage part, and the control circuit identically applies a switch on/off signal to each of the first switch and the second switch, and selectively applies a switch on/off signal to either the third switch or the fourth switch based on a magnitude of an input voltage input through the AC voltage part.
