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