Patent ID: 11909195
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 6:
7. 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,
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, and

a second comparison module configured to:
compare the output current with second reference current larger than the first reference current, and
transmit a second detection result in which the output current exceeds the second reference current to the power conversion unit.
