Abstract: The present invention provides a rectifying device with a power factor correction (PFC) function. To solve the power factor problem and smooth the DC power, the present invention stops the operation of switching an inductor between ground and a capacitor at high speed in a high voltage portion of an unsmoothed DC input voltage where current distribution is not required and boosts the voltage by rapidly switching the inductor between the ground and the capacitor only in a low voltage portion of the unsmoothed DC input voltage that requires current distribution, thereby improving the power factor and smoothing the DC power without excessively boosting the voltage. Therefore, since the present invention does not cause an excessive voltage increase, it is possible to reduce the stress caused by the high voltage in the circuit internal components and suppress the noise generated by the switching. In addition, as a result, the safety and reliability of a circuit can be improved, and the size of the component, which is proportionally increased as the operating voltage increases, can be reduced, thereby reducing the size of the component and the size of the entire rectifying device. The rectifying device comprises a rectifying unit, an inductor, a capacitor, a switch, a switch control unit, a switching element, and a PFC control unit.
