Abstract

Embodiments of this application provide a charging system and a charging device. The charging system includes a direct current bus, an AC-DC conversion circuit, a DC-DC conversion circuit, a plurality of power supply circuits, and an inductor group. The AC-DC conversion circuit is configured to: convert a received alternating current into a direct current, and then output the direct current to the DC-DC conversion circuit through the direct current bus. Each power supply circuit includes a direct current power supply and a ground capacitor, the direct current power supply is connected to the direct current bus through the ground capacitor, and the direct current power supply is configured to output a direct current to the DC-DC conversion circuit through the direct current bus. The DC-DC conversion circuit is configured to: perform power conversion on the direct current obtained from the direct current bus, and then output the converted direct current. In addition, the direct current bus is connected to the AC-DC conversion circuit through the inductor group, or the direct current bus is connected to each power supply circuit through the inductor group. In embodiments of this application, running reliability of the charging system can be improved when the direct current bus is connected to the plurality of power supply circuits.
