CHARGING DEVICE

摘要

PURPOSE: A charging apparatus is provided to freely vary a voltage or current by including a mesh structure for connecting an AC/DC converter in series or parallel. CONSTITUTION: A charging pack includes an AC terminal, an AC/DC converter, and a DC terminal. AC power is inputted to the AC terminal. The AC/DC converter rectifies the AC power into DC power. The DC terminal outputs the DC power of a first power value. A mesh structure controls a serial connection status of the charging pack, a parallel connection status of the charging pack, and the on/off of the charging pack. A charging module(200a-200k) includes a charging module controller which individually controls the on/off of the charging pack. A charging unit(300) connects a plurality of charging modules in series or parallel.
