Abstract:
A charging circuit and a mobile terminal are provided. The charging circuit is coupled between a charging interface and a battery of a mobile terminal. The charging circuit includes a first circuit, a capacitive coupling element, and a second circuit connected in series between the charging interface and the battery. The capacitive coupling element is configured to disconnect a direct current (DC) path of the charging circuit. The capacitive coupling element includes at least one capacitor and the capacitor of the capacitive coupling element is one of the following capacitors: a capacitor composed of a printed circuit board (PCB) and a capacitor composed of a flexible printed circuit (FPC) board. A size, shape, or thickness of the capacitor of the capacitive coupling element is designed based on a structure of the mobile terminal.

Claim (Index 1):
A charging circuit, coupled between a charging interface and a battery of a mobile terminal, the charging circuit comprising a first circuit, a capacitive coupling element, and a second circuit connected in series between the charging interface and the battery, the capacitive coupling element being configured to disconnect a direct current (DC) path of the charging circuit, the capacitive coupling element comprising at least one capacitor and the capacitor of the capacitive coupling element is one of the following capacitors: a capacitor composed of a printed circuit board (PCB) and a capacitor composed of a flexible printed circuit (FPC) board, and a size, shape, or thickness of the capacitor of the capacitive coupling element being designed based on a structure of the mobile terminal, wherein\n the first circuit comprises a bridge-arm circuit and a control circuit controlling the bridge-arm circuit, the bridge-arm circuit is provided with a switch transistor with a lower on-resistance to reduce heating and loss and improve energy transfer efficiency of the whole charging circuit, and the bridge-arm circuit is configured to be connected with the charging interface and perform at least one of charging and discharging on the capacitor of the capacitive coupling element under control of the control circuit to convert a DC to an alternating current (AC), wherein the DC is output from the charging interface and is used for charging; and the second circuit is configured to adjust the AC to a DC suitable for charging the battery, wherein the AC is coupled to the second circuit by the first circuit through the capacitive coupling element.
