Abstract
The present application relates to systems and methods for regulating power for one or more electronic devices. In accordance with aspects of the disclosure, one or more micro-controllers are configured to regulate both peak and average power being consumed by devices within the system. The power being consumed within the system can be determined over different durations of time and multiple independent feedback loops may be used to regulate power within the system. In addition, the system can include a feedback loop that is configured to allow the system to enter into a low-power mode.
Claims20
A method of power regulation comprising:
- receiving input indicative of power usage for one or more components;
- determining first power-usage values associated with a first span of time and second power-usage values associated with a second span of time;
- providing the first power-usage values to a first control loop that performs a comparison with a first reference-power set point and the second power-usage values to a second control loop that performs a comparison with a second reference-power set point;
- and
- transmitting a power signal for regulating power usage by the one or more components so as to produce power usage that is within the first reference-power set point and the second reference-power set point.
A system for power regulation comprising:
- one or more computing devices;
- a programmable integrated-circuit that is configured to:
- receive input indicative of power usage for one or more computing devices;
- determine first power-usage values associated with a first span of time and second power-usage values associated with a second span of time;
- provide the first power-usage values to a first control loop that performs a comparison with a first reference-power set point and the second power-usage values to a second control loop that performs a comparison with a second reference-power set point;
- and
- transmit a power signal for regulating power usage by the one or more computing devices so as to produce power usage that is within the first reference-power set point and the second reference-power set point.
