A power factor correction apparatus with an embedded direct-current to direct-current (DC-DC) converter is provided. The apparatus includes a power factor controller, a high-voltage adapter and a low-voltage adapter. The power factor controller, which receives an AC power source, includes a transformer. The secondary side of the transformer includes a first sub-coil and a second sub-coil for outputting a first power source and a second power source respectively. The high-voltage adapter converts the first power source into a high DC power source. The low-voltage adapter converts the second power source into a first DC power source. The power factor controller corrects the power factor of the power factor correction apparatus according to the first DC power source.
