  "textContent": "An apparatus for wireless power transfer includes a resonant circuit comprising: a transmitter coil; a first capacitor connected with the transmitter coil in series; and a second capacitor connected in series with a first switch. The second capacitor and the first switch are connected in parallel with the first capacitor. A control circuit is connected to the resonant circuit, and is configured to: detect whether an event of a voltage across the first capacitor or a current of the transmitter coil occurs; and when detecting that the event occurs, control to turn on the first switch in response to a signaling of turning on the first switch. A method for controlling switching-in of the second capacitor is also provided.",
