ELECTRONIC DEVICE WIRELESSLY RECEIVING POWER, AND OPERATING METHOD THEREFOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18093088 titled 'ELECTRONIC DEVICE WIRELESSLY RECEIVING POWER, AND OPERATING METHOD THEREFOR

Simplified Explanation

An electronic device is described in this patent application. The device includes various components such as a battery, a resonant circuit with a receiving coil, capacitors, and switches, a rectifier circuit, a DC/DC converter, a charge control circuit, and a controller. The controller is responsible for monitoring the voltage output from the rectifier circuit and controlling the switches accordingly.

• The controller checks the voltage output from the rectifier circuit.
• If the voltage is equal to or greater than a threshold voltage, the controller controls the switches to form a serial resonant circuit with the receiving coil and capacitors.
• If the voltage is less than the threshold voltage, the controller controls the switches to form a parallel resonant circuit with the receiving coil and capacitors.

Potential applications of this technology:

• Wireless charging systems for electronic devices.
• Power transfer systems for electric vehicles.
• Inductive charging pads for smartphones and other portable devices.

Problems solved by this technology:

• Efficiently transferring power wirelessly.
• Optimizing the resonant circuit based on the voltage output.
• Ensuring proper charging and power transfer.

Benefits of this technology:

• Improved charging efficiency.
• Flexibility in adapting to different voltage levels.
• Enhanced control over power transfer.
• Compatibility with various electronic devices.
