Abstract: Techniques for providing an uninterruptible power supply are disclosed. An example system includes three single-phase Uninterruptible Power Supplies (UPSs) and an adapter. The adapter is to receive three-phase AC power, and separate the three-phase AC power into three separate single-phase outputs. Each single-phase output is coupled to an input of one of the three single-phase UPSs. An output of each one of the single-phase UPSs is coupled to one of three single-phase inputs of the adapter, and the adapter is to combine the three single-phase inputs into a single three-phase output.

Abstract: Example implementations relate to concurrent alternating-current and direct-current. In one example, a device comprises a power module connected to a first power outlet, the power module connected to a second power outlet, and a controller to the power module to concurrently provide alternating-current (AC) power to the first power outlet and direct-current (DC) power to the second power outlet by switching a transistor including switching circuitry in response to an absence of AC input power to the device.

Abstract: According to an example, a battery is charged using a charge voltage based on a present state of charge of the battery and a present ambient temperature of the battery. Additionally, the charge voltage may be based on the present state of charge of the battery, the present ambient temperature of the battery, and an age of the battery. The charge voltage may be retrieved from a lookup table that includes a plurality of reference charge voltage values at which to charge the battery for different ambient temperatures, different states of charge, or different ages of the battery.

Abstract: In various examples, a system comprises a rack-mountable power distribution unit (PDU). The PDU may: receive an alternating current (AC) power feed, convert the AC to a direct current (DC) power pool, determine an amount of available amount of power of the DC power pool to be delivered to devices electrically coupled to the PDU, and output the DC power pool to the devices coupled to the PDU based on the amount of available power.
