摘要

A power-delivery system may comprise a load device and a direct-current converter configured to deliver current to the load device when the direct-current converter is in an on state. The power-deliver system may comprise a voltage-measurement system configured to measure, at a beginning of each measurement cycle in a cyclic measurement pattern, a voltage at the load device. The power-deliver system may comprise a power controller configure to receive, at the beginning of each measurement cycle, the measurement of the voltage, and to perform, at the beginning of a control cycle in a cyclic control pattern, a voltage-control decision in response to a change in the measurement of the voltage being below a voltage-change threshold. The voltage-control decision may comprise whether to switch the state of the first direct-current converter. The cyclic control pattern may operate at a first frequency, and the measurement pattern may operate at a second frequency.

說明書

The Memory 720 of the Computer System 701 may be comprised of a Memory Controller 722 and one or more memory modules for temporarily or permanently storing data (not depicted). In some embodiments, the Memory 720 may comprise a random-access semiconductor memory, storage device, or storage medium (either volatile or non-volatile) for storing data and programs. The Memory Controller 722 may communicate with the Processor 710, facilitating storage and retrieval of information in the memory modules. The Memory Controller 722 may communicate with the I/O Interface 730, facilitating storage and retrieval of input or output in the memory modules. In some embodiments, the memory modules may be dual in-line memory modules.

The I/O Interface 730 may comprise an I/O Bus 750, a Terminal Interface 752, a Storage Interface 754, an I/O Device Interface 756, and a Network Interface 758. The I/O Interface 730 may connect the Main Bus 740 to the I/O Bus 750. The I/O Interface 730 may direct instructions and data from the Processor 710 and Memory 720 to the various interfaces of the I/O Bus 750. The I/O Interface 730 may also direct instructions and data from the various interfaces of the I/O Bus 750 to the Processor 710 and Memory 720. The various interfaces may comprise the Terminal Interface 752, the Storage Interface 754, the I/O Device Interface 756, and the Network Interface 758. In some embodiments, the various interfaces may comprise a subset of the aforementioned interfaces (e.g., an embedded computer system in an industrial application may not include the Terminal Interface 752 and the Storage Interface 754).
