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

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
