  "textContent": "A power supply circuit and a power supply device, and the power supply circuit includes a bridge switching circuit, a transformer, a resonant circuit, a rectifier circuit. The bridge switching circuit, the transformer, the resonant circuit, and the rectifier circuit are sequentially connected in series. The resonant circuit includes an induction coil connected in series between the transformer and the rectifier circuit. In the case that the inductive coil is connected in series in the circuit, the inductive coil can participate in conductive charging as an inductor in the resonant circuit. Further, the inductive coil can also receive the inductive voltage wirelessly transmitted by the external circuit through electromagnetic induction, and the inductive voltage can be transmitted to the load through the rectifier circuit to achieve inductive charging.",
