Abstract: A computing device is associated with a circuit for sharing and distributing backup power. During normal operating conditions, a main bus bar provides power to each computing device in a rack via a main power bus of the corresponding circuit. In the event of an AC power outage, the main power bus is deactivated and a backup power path of the circuit is activated. Backup power is provided to the device from a battery of the circuit via the backup power path. A shared power path is also activated in the circuit such that backup power may be provided from the battery to the main bus bar. By providing backup power to the main bus bar, the other computing devices in the rack that do not have sufficient backup power may receive backup power from the main bus bar until AC power is restored.
Abstract translation: 计算设备与用于共享和分发备用电力的电路相关联。 在正常操作条件下，主母线通过相应电路的主电源总线为机架中的每个计算设备供电。 在交流电停电的情况下，主电源总线被停用，电路的备用电源路径被激活。 通过备用电源路径从电路的电池向设备提供备用电源。 在电路中也激活共享电源路径，使得备用电源可以从电池提供到主母线。 通过为主母线提供备用电源，机架中没有足够备用电源的其他计算设备可能会从主母线接收备用电源，直到电源恢复。

Abstract: Aspects of the disclosure relate generally to uninterruptible power supply units for systems requiring back up power. Each unit may include UPS circuitry for controlling charging and allowing discharging of a battery. The UPS circuitry may includes a controller and a plurality of metal-oxide semiconductor field effect transistors (“MOSFET”) switches. The MOSFETs may include charging and discharging MOSFETs arranged in series with the battery all driven by a single gate driver, such as a controller. In this regard, the controller may limit the charging current though all of the MOSFETs and charge the battery. The MOSFETs may be arranged such that if the charging MOSFET fails, the redundant charging MOSFET may continue to limit the charging current to the battery. Similarly, a redundant discharging MOSFET may be arranged in series with a discharging MOSFET in order to continue to provide discharging current if the discharging MOSFET fails.
