ELECTRONIC DEVICE COMPRISING CHARGING CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18107071 titled 'ELECTRONIC DEVICE COMPRISING CHARGING CIRCUIT

Simplified Explanation

The abstract describes an electronic device that includes a battery and a receive coil for wirelessly receiving power from an external power device. The device also includes a power management module that includes a rectifier circuit, a charging circuit, and a rectifying capacitor. The power management module generates a sync signal based on the current flowing in the rectifier circuit and controls the operation of switches in the charging circuit based on this sync signal.

  • The electronic device has a battery and a receive coil for wirelessly receiving power.
  • The power management module includes a rectifier circuit, a charging circuit, and a rectifying capacitor.
  • The rectifier circuit rectifies the current from the receive coil and provides an output terminal.
  • The charging circuit charges the battery using the output terminal of the rectifier circuit.
  • The power management module generates a sync signal based on the current in the rectifier circuit.
  • The sync signal controls the operation of switches in the charging circuit or their switching frequencies.

Potential applications of this technology:

  • Wireless charging of electronic devices.
  • Power management for portable devices.
  • Integration into smart home systems.

Problems solved by this technology:

  • Eliminates the need for wired charging, providing convenience and flexibility.
  • Efficiently manages power flow from an external power device to the battery.
  • Enables wireless charging in various electronic devices.

Benefits of this technology:

  • Simplifies the charging process by eliminating the need for cables.
  • Provides a more efficient and reliable power management system.
  • Enhances the portability and usability of electronic devices.
  • Enables seamless integration into wireless charging infrastructure.


Original Abstract Submitted

In accordance with an aspect of the disclosure, an electronic device comprises: a battery; a receive coil configured to wirelessly receive power from a transmit coil of an external power device; and a power management module electrically connected with the battery and the receive coil, wherein the power management module includes: a rectifier circuit configured to rectify current flowing in the receive coil, the rectifier circuit including an output terminal; a charging circuit configured to charge the battery including a plurality of switches and an input terminal, the input terminal connected to the output terminal of the rectifier circuit; and a rectifying capacitor electrically connected with the output terminal of the rectifier circuit and the input terminal of the charging circuit, and wherein the power management module generates a sync signal based on current flowing in the output terminal of the rectifier circuit and controls whether the plurality of switches operate or switching frequencies of the plurality of switches, based on the sync signal.
