本发明公开一种能够减少低频漏电流的充电装置,该充电装置包括占空比控制器,该占空比控制器基于从外部充电设备提供的AC电力的AC电压的共模分量的电平、由DC链路电容器形成的DC电压的电平以及从输入端子Y‑电容器的连接节点和输出端子Y‑电容器的连接节点流到地的漏电流来确定功率因数校正转换器中的开关元件的占空比。

    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.
