Disclosed is a charging apparatus capable of reducing a low-frequency leakage current, the charging apparatus including a duty controller that determines the duty of a switching element in a power factor correction converter on the basis of the level of a common-mode component of an AC voltage of AC power provided from an external charging facility, the level of the DC voltage formed by a DC link capacitor, and a leakage current flowing from the connection node of input-terminal Y-capacitors and the connection node of output-terminal Y-capacitors to the ground.
