Electronic device with overcurrent protection and method for overcurrent protection

An electronic device comprising:

• at least one power converter,
• wherein the at least one power converter comprises:
• a power conversion unit configured to convert an input voltage or an input current to supply an output current, and
• an overcurrent protection unit configured to:
• detect the output current, and
• transmit a detection result to the power conversion unit to adjust the output current, and
• wherein the overcurrent protection unit comprises:
• an overcurrent extraction module configured to output a difference between the output current exceeding a designated first reference current and the designated first reference current,
• a calculation module configured to calculate an accumulative value obtained by integrating the difference with respect to time, and
• a first comparison module configured to:
• compare the accumulative value with a designated critical value, and
• transmit a first detection result in which the accumulative value exceeds the designated critical value to the power conversion unit.

An overcurrent protection method of an electronic device, the method comprising:

• converting an input voltage or an input current to supply an output current;
• outputting a difference between the output current exceeding a designated first reference current and the designated first reference current;
• calculating an accumulative value obtained by integrating the difference with respect to time;
• and
• comparing the accumulative value with a designated critical value and transmitting a first detection result in which the accumulative value exceeds the designated critical value.
