HYBRID CONTROL METHODS FOR UNINTERRUPTIBLE POWER SUPPLIES

摘要

Various embodiments of the present technology provide methods for determining a status of power supplies to a server system and dynamically managing an uninterruptible power system (UPS) of the server system between an off-line mode and an on-line mode based upon the status of the power supplies. The UPS requires a minimum standby power during the off-line mode while requires no switch time to continuously supply power to loads of the server system during the on-line mode. Some embodiments determine a status of an AC input power to a server system and, in response to detecting an abnormal condition associated with the AC input power, generate a power warning signal. The power warning signal can cause an UPS of the server system to be switched from an off-line mode to an on-line mode.

主权项

1. A server system, comprising:
at least one processor; and memory including instructions that, when executed by the at least one processor, cause the system to:
determine a status of power supplies to components of the server system;determine whether an abnormal condition has occurred with at least one of the power supplies;in response to determining that the abnormal condition has occurred, cause an uninterruptible power system (UPS) of the server system to be switched from an off-line mode to an on-line mode;andcause the UPS to supply power to the components of the server system when an output voltage of a power supply unit (PSU) of the server system is determined to be below an output voltage of the UPS.
