Power supply controllers
Example implementations relate to power supply controllers. In some examples, a controller can include instructions to: set a power threshold for a power supply coupled to a computing component when the computing component is operating in a first state, determine when the computing component is alternating from the first state to a second state, and allow the power supply to exceed the power threshold for a fixed period of time in response to the computing component alternating from the first state to the second state.
1. A system, comprising:
a power supply coupled to a plurality of computing components by a single power rail;
a first timer to determine a quantity of time the power supply has continuously exceeded a power threshold;
a second timer to determine a quantity of time the power supply has continuously been below the power threshold; and
a controller, comprising instructions to:
stop the first timer when the second timer has reached a first time limit;
stop the second timer when the power supply has exceeded the power threshold; and
deactivate the power supply when the first timer reaches a second time limit.
2. The system of claim 1 , wherein the controller includes instructions to:
set the first timer to zero when the second timer has reached the first time limit; and
set the second timer to zero when the power supply has exceeded the power threshold.
3. The system of claim 1 , wherein the controller includes instructions to alter a load of the plurality of computing components to prevent the first timer from reaching the second time limit.
4. A controller, comprising instructions to:
set a first timer to determine a quantity of time a power supply has continuously exceeded a power threshold;
set a second timer to determine a quantity of time the power supply has continuously been below the power threshold;
stop the first timer when the second timer has reached a first time limit;
stop the second timer when the power supply has exceeded the power threshold; and
deactivate the power supply when the first timer reaches a second time limit.
5. The controller of claim 4 , wherein the power supply is coupled to the computing component through a single power rail.
6. The controller of claim 4 , comprising instructions to alter a load of a computing component below the power threshold when the first timer reaches a second time limit.
7. The controller of claim 4 , comprising instructions to:
set the first timer to zero when the second timer reaches a first time limit; and
set the second timer to zero when the power supply has exceeded the power threshold.
8. A non-transitory machine-readable storage medium having stored thereon machine-readable instructions to cause a computer processor to:
set a first timer to determine a quantity of time a power supply has continuously exceeded a power threshold;
set a second timer to determine a quantity of time the power supply has continuously been below the power threshold;
stop the first timer when the second timer has reached a first time limit;
stop the second timer when the power supply has exceeded the power threshold; and
deactivate the power supply when the first timer reaches a second time limit.
9. The medium of claim 8 , comprising instructions to restart the first timer when the second timer has reached a first time limit.
10. The medium of claim 8 , comprising instructions to restart the second timer when the power supply has exceeded the power threshold.
11. The medium of claim 8 , comprising instructions to alter a load of the plurality of computing components before the first timer reaches the second time limit.
12. The medium of claim 8 , wherein the power supply is coupled to the computing component through a single power rail.
