ELECTRONIC DEVICE FOR CARRYING OUT OVERVOLTAGE PROTECTION OPERATION AND CONTROL METHOD THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17970216 titled 'ELECTRONIC DEVICE FOR CARRYING OUT OVERVOLTAGE PROTECTION OPERATION AND CONTROL METHOD THEREFOR
Simplified Explanation
The abstract describes an electronic device that includes a resonance circuit, rectifier, DC/DC converter, charger, OVP circuits, detection circuit, control circuit, and communication circuit. The control circuit controls the OVP circuits based on the detected rectified voltage to connect or disconnect the coil and capacitor.
- The electronic device includes a resonance circuit that receives power wirelessly.
- The rectifier converts AC power from the resonance circuit to DC power.
- The DC/DC converter converts and outputs the DC power from the rectifier.
- The charger uses the converted power to charge the battery.
- The first OVP circuit selectively connects the coil to the capacitor.
- The second OVP circuit is connected in parallel to the first OVP circuit.
- The detection circuit detects the rectified voltage.
- The control circuit controls the first OVP circuit based on the detected voltage.
- The communication circuit enables communication with other devices.

Original Abstract Submitted
An electronic device may include: a resonance circuit which comprises a battery, a coil and a capacitor, and receives power wirelessly; a rectifier which rectifies AC power, provided from the resonance circuit, to DC power; a DC/DC converter which converts and outputs the DC power provided from the rectifier; a charger which charges the battery by using the converted power provided from the DC/DC converter; a first OVP circuit which selectively connects the coil to the capacitor; a second OVP circuit which is connected in parallel to the first OVP circuit; a detection circuit which detects a rectified voltage; a control circuit; and a communication circuit, wherein the control circuit, on the basis that the detected rectified voltage is equal to or greater than a first threshold voltage, controls the first OVP circuit so as to be in an off state so that the coil is not connected to the capacitor, and on the basis that the detected rectified voltage is less than a second threshold voltage, controls the first OVP circuit so that the first OVP circuit is switched from the off state to an on state so that the coil is connected to the capacitor, wherein the second threshold voltage may be smaller than the first threshold voltage.
