CHARGING CIRCUITRY WITH THREE-LEVEL CONVERTER AND METHOD FOR CONTROLLING BALANCING IN THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17968144 titled 'CHARGING CIRCUITRY WITH THREE-LEVEL CONVERTER AND METHOD FOR CONTROLLING BALANCING IN THE SAME

Simplified Explanation

The patent application describes a charging circuit for an electronic device that includes a three-level converter and a balancing circuit. The charging circuit is used to charge the device's battery.

  • The charging circuit includes a switching circuit with multiple switching elements and a flying capacitor, and a filter circuit with an inductor and a capacitor.
  • The balancing circuit is responsible for maintaining or switching the balancing control direction during a designated mode of balancing.
  • The balancing control circuit generates an output based on whether the balancing corresponds to targeted balancing, and the output is used to maintain or switch the balancing control direction.
  • The switching control circuit performs switching for the switching elements in the balancing control direction or in a direction reverse to the balancing control direction, based on the output of the balancing control circuit.

Potential applications of this technology:

  • This charging circuit can be used in various electronic devices such as smartphones, tablets, laptops, and electric vehicles.
  • It can improve the efficiency and reliability of the charging process, ensuring that the battery is charged properly.

Problems solved by this technology:

  • The three-level converter and balancing circuit address the issue of unbalanced charging in the battery, which can lead to reduced battery life and performance.
  • The balancing control circuit and switching control circuit ensure that the balancing is maintained or switched correctly during the charging process.

Benefits of this technology:

  • The three-level converter and balancing circuit provide a more efficient and reliable charging process, resulting in improved battery life and performance.
  • The balancing control circuit and switching control circuit allow for better control and management of the balancing process, ensuring that the battery is charged evenly.
  • This technology can help extend the overall lifespan of the battery, reducing the need for frequent replacements.


Original Abstract Submitted

A charging circuit of an electronic device having a three-level converter, and a method and a device for controlling balancing in a charging circuit are provided. The electronic device includes a battery, at least one processor, and a charging circuit. The charging circuit includes, as a three-level converter, a switching circuit including multiple switching elements and a flying capacitor, and a filter circuit including an inductor and a capacitor. The charging circuit includes, as a balancing circuit, a balancing control circuit configured to, during balancing corresponding to a designated a mode, based on whether the balancing corresponds to targeted balancing, generate an output for maintaining or switching a balancing control direction configured for the designated mode, and a switching control circuit configured to perform switching for the switching elements in a balancing control direction corresponding to the designated mode, based on an output of the balancing control circuit, or perform switching for the switching elements in a direction reverse to a balancing control direction corresponding to the designated mode.
