Abstract: An apparatus for wireless charging includes a charger, a wireless transmitting controller and a transmitting coil. The charger is configured to output a first voltage to the wireless transmitting controller. The wireless transmitting controller is configured to boost the first voltage to obtain a second voltage, and the second voltage is greater than the first voltage.

Abstract: A wireless charging reception circuit, a method, electronic device and a wireless charging system are described. In the wireless charging reception circuit, a control circuit may control a rectifying circuit to rectify electric signals transmitted by a first resonance circuit and/or a second resonance circuit. Since the rectifying circuit outputs different voltages after rectifying the electric signals transmitted by the different resonance circuits, the control circuit may controls the rectifying circuit to rectify the electric signals transmitted by the different resonance circuits to adjust the output voltages of the rectifying circuit.
