Abstract

A wireless charging device is provided in this disclosure, which includes a resonant network, an inverter circuit, and a controller. The resonant network includes a resonant capacitor and a transmitting coil. An input end of the inverter circuit is configured to connect to a direct current power supply, and an output end of the inverter circuit is configured to connect to the resonant network. The controller is configured to determine a moving direction of the transmitting coil based on a self-inductance of the transmitting coil or a resonant frequency of the resonant network, and control a movement of the transmitting coil based on the moving direction of the transmitting coil, to enable the wireless charging device to align with the electronic device.
