CHARGER INTEGRATED CIRCUIT INCLUDING BIDIRECTIONAL SWITCHING CONVERTER, AND ELECTRONIC DEVICE INCLUDING THE CHARGER INTEGRATED CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17985301 titled 'CHARGER INTEGRATED CIRCUIT INCLUDING BIDIRECTIONAL SWITCHING CONVERTER, AND ELECTRONIC DEVICE INCLUDING THE CHARGER INTEGRATED CIRCUIT

Simplified Explanation

The abstract describes a charger integrated circuit that includes a bidirectional switching converter and a controller. The bidirectional switching converter consists of four switching elements, an inductor, and a capacitor. The controller generates PWM signals based on sensing signals from the converter and controls the switching elements accordingly.

  • The bidirectional switching converter is designed to efficiently convert power in both directions.
  • The inductor and capacitor are key components in the converter circuit.
  • The controller generates PWM signals to control the switching elements based on the sensed signals.
  • The first PWM signal controls the first and fourth switching elements when the average inductor current is positive.
  • The second PWM signal controls the second and third switching elements.
  • The controller can generate the first and second switching signals based on the opposite PWM signals when the average inductor current is negative.

Potential Applications

  • This charger integrated circuit can be used in various electronic devices that require efficient bidirectional power conversion, such as electric vehicles, renewable energy systems, and portable electronic devices.

Problems Solved

  • The bidirectional switching converter solves the problem of inefficient power conversion in both directions.
  • The controller's ability to generate PWM signals based on sensing signals allows for precise control of the switching elements, improving overall efficiency.

Benefits

  • The bidirectional switching converter and controller combination provides efficient power conversion in both directions.
  • The use of PWM signals and precise control of the switching elements improves overall efficiency.
  • The integrated circuit design allows for compact and cost-effective implementation in various electronic devices.
