Abstract: Various embodiments of the present technology provide methods for testing one or more components of a power supply unit (PSU) of a server system to identify potential issues before the PSU actually fails. Some embodiments provide systems and methods for determining a value of a performance characteristic (e.g., a current, voltage or impedance) of one or more components of a PSU of a server system. Thereafter, in response to the value of the performance characteristic being inconsistent with a predetermined criterion, the systems and methods involve generating a corresponding alarm signal.

Abstract: 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.
Abstract translation: 本技术的各种实施例提供了用于确定服务器系统的电力供应状况的方法，并且基于在离线模式和在线模式之间动态地管理服务器系统的不间断电力系统（UPS） 电源。 在离线模式期间，UPS需要最小待机功率，而在在线模式期间不需要切换时间来连续向服务器系统的负载供电。 一些实施例确定到服务器系统的AC输入功率的状态，并且响应于检测到与AC输入功率相关联的异常状况，生成电力警告信号。 电源警告信号可能导致服务器系统的UPS从离线模式切换到在线模式。

Abstract: A system and method for current balancing from a three-phase AC power source is disclosed. The system includes power supply units, each having inputs coupled to one output of the three phase power source, and a neutral conductor. Multiple loads are each coupled to a DC output of one of the power supply units. Each of the loads include a component having adjustable power consumption. A controller is coupled to each of the power supply units and each of the loads. The controller is operable to compare the power consumption of each of the loads to an average value. The controller adjusts the power consumption of at least one of the loads to balance the power consumption between the loads.

Abstract: Various examples of the present disclosure provide a high efficient battery backup (BBU) system and systems and methods for managing the BBU system through a microcontroller unit (MCU) and an ORing FET system of the BBU system. In some examples, a baseboard management controller (BMC) of a server system is used to control the MCU and the ORing FET system of the BBU system such that the BBU system can operate in multiple operating modes without a battery discharger. The operating modes of the BBU system includes, but are not limited to, a battery constant-current-charging mode, a battery constant-voltage-charging mode, a battery discharging mode, or a battery capacity calibration mode.

Abstract: Various examples of the present disclosure provide a high efficient battery system, and systems and methods for intelligently discharging and charging the battery system such that an output voltage of the battery system is maintained within a predetermined voltage range. In some examples, a base board controller (BMC) is used to manage charging and discharging of the battery system. The BMC can provide both over-charging protection and over-discharging protection for the battery system.

Abstract: The present disclosure provides a system and method for dynamically defining a specific input pin of a management controller (e.g., a baseboard management controller (BMC)) of a server system in response to a new device being plugged into the server system. The new device comprises one of a power supply unit (PSU), an automatic transfer switch (ATS), or a battery backup unit (BBU) of the server system. In some implementations, the PSU, the ATS, and the BBU are modularized into a plurality of ATS modules, a plurality of PSU modules, and a plurality of BBU modules, respectively. Each of the plurality of ATS modules, the plurality of PSU modules, and the plurality of BBU modules has substantially the same physical size.
