1. A power factor correction circuit correcting a power factor of AC voltage, comprising:

  • a rectifying unit stopping rectifying the AC voltage in a transient state and generating an rectified voltage by rectifying the AC voltage in a steady state;

    a power factor correction unit generating a power-factor-corrected voltage by correcting the rectified voltage;

    a smoothing unit generating a smoothed voltage by smoothing the power-factor-corrected voltage; and

    an inrush current limiting unit providing a limited current by limiting an inrush current generated by the AC voltage in the transient state and stopping providing a current to the smoothing unit.
