1. A charging circuit, comprising a first circuit, a capacitive coupling element, and a second circuit connected in series, the capacitive coupling element configured to disconnect a direct-current (DC) path of the charging circuit, wherein
the first circuit comprises a bridge-arm circuit and a control circuit controlling the bridge-arm circuit, the bridge-arm circuit configured to connect with a charging interface and perform at least one of charging and discharging one or more capacitors in the capacitive coupling element under control of the control circuit to convert DC, which is output from the charging interface and is used for charging, to alternating current (AC); and the second circuit is configured to adjust the AC, which is coupled to the second circuit by the first circuit through the capacitive coupling element, to DC which is suitable for charging of a battery. |
