  "textContent": "A charging module includes a low-frequency resonant unit, a high-frequency resonant unit, a first capacitor, a rectifier unit and a voltage conversion unit. The low-frequency resonant unit comprises a low-frequency coil and a low-frequency compensation capacitor connected in series. The high-frequency resonant unit comprises a high-frequency coil and a high-frequency tuning capacitor connected in series. The high-frequency tuning capacitor is used to make the difference between the AC voltage between two terminals of the high-frequency resonant unit when receiving high-frequency wireless power signals and the induced electromotive force between two terminals of the low-frequency coil generated by the current flowing through the high-frequency resonant unit is within a preset interval.",
