ELECTRONIC DEVICE WITH OVERCURRENT PROTECTION AND METHOD FOR OVERCURRENT PROTECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17046133 titled 'ELECTRONIC DEVICE WITH OVERCURRENT PROTECTION AND METHOD FOR OVERCURRENT PROTECTION
Simplified Explanation
The abstract describes an electronic device with an overcurrent protection function. It includes a power converter that converts input voltage or current to supply output current, a control unit to adjust the output current, and an overcurrent protection unit to detect and transmit the output current information to the control unit.
- The overcurrent protection unit includes an overcurrent extraction module that calculates the difference between the output current and a designated first reference current.
- A calculation module integrates the difference over time to obtain an accumulative value.
- A first comparison module compares the accumulative value with a critical value and transmits a detection result to the control unit if the accumulative value exceeds the critical value.
Potential applications of this technology:
- Power supply systems: This overcurrent protection function can be used in various power supply systems to prevent damage caused by excessive current.
- Electronic devices: The electronic device with this overcurrent protection function can be used in various electronic devices such as smartphones, laptops, and home appliances.
Problems solved by this technology:
- Overcurrent protection: The device provides a mechanism to detect and protect against overcurrent situations, preventing damage to the device or connected components.
- Accurate detection: The integration of the difference between output current and reference current over time allows for more accurate detection of overcurrent situations.
Benefits of this technology:
- Enhanced safety: The overcurrent protection function ensures the device and connected components are protected from potential damage caused by excessive current.
- Improved reliability: Accurate detection of overcurrent situations allows for timely intervention and prevention of potential failures or malfunctions.
- Efficient power management: The control unit can adjust the output current based on the detection results, optimizing power usage and improving overall efficiency.
Original Abstract Submitted
An electronic device having an overcurrent protection function is provided. The electronic device includes at least one power converter, the at least one power converter including a power conversion unit to convert input voltage or input current to supply output current, a control unit to adjust the output current, and an overcurrent protection unit to detect the output current and transmit a detection result to the control unit, and wherein the overcurrent protection unit includes an overcurrent extraction module to output a difference between the output current exceeding designated first reference current and the first reference current; a calculation module to calculate an accumulative value obtained by integrating the difference with respect to time, and a first comparison module to compare the accumulative value with a designated critical value and to transmit a first detection result in which the accumulative value exceeds the critical value to the control unit.
