Abstract
Systems and methods are provided for overcurrent protection in a power supply. In some embodiments, the method comprises determining a load of the power supply; selecting an over-current limit, among a plurality of the over-current limits, based on the measured load of the power supply; and responsive to an input current of the power supply, an output current of the power supply, or both exceeding the identified over-current limit, taking one or more overcurrent protection measures.
Claims14
A method for a power supply, the method comprising:
- determining a load of the power supply;
- receiving an indication of a planned increase in the load of the power supply;
- selecting an over-current limit, among a plurality of over-current limits, based on the planned increase in the load of the power supply;
- and
- responsive to an input current of the power supply, an output current of the power supply, or both exceeding the selected over-current limit, taking the one or more overcurrent protection measures prior to the increase in the load of the power supply.
A system, comprising:
- a hardware processor;
- and
- a non-transitory machine-readable storage medium encoded with instructions executable by the hardware processor to perform a method comprising:
- determining a load of the power supply;
- receiving an indication of a planned increase in the load of the power supply;
- selecting an over-current limit, among a plurality of over-current limits, based on the planned increase in the load of the power supply;
- and
- responsive to an input current of the power supply, an output current of the power supply, or both exceeding the selected over-current limit, taking the one or more overcurrent protection measures prior to the increase in the load of the power supply.
A non-transitory machine-readable storage medium encoded with instructions executable by a hardware processor of a computing component, the machine-readable storage medium comprising instructions to cause the hardware processor to perform a method comprising:
- determining a load of the power supply;
- selecting an over-current limit, among a plurality of the over-current limits, based on the determined load of the power supply;
- responsive to an input current of the power supply, an output current of the power supply, or both exceeding the identified over-current limit, taking one or more overcurrent protection measures;
- receiving an indication of a planned increase in the load of the power supply;
- selecting a second over-current limit of the over-current limits based on the planned increase in the load of the power supply;
- and
- responsive to an input current of the power supply, an output current of the power supply, or both exceeding the selected second over-current limit, taking the one or more overcurrent protection measures prior to the increase in the load of the power supply.
