Abstract: Examples disclosed herein relate to dual in-line memory module (DIMM) battery backup. Some examples disclosed herein describe systems that include a backup power source pluggable into a DIMM slot. The backup power source may include a plurality of battery cells electrically connected to a DIMM to provide backup power to the DIMM. Each of the plurality of battery cells supporting the DIMM may be electrically connected to a DC-to-DC converter in series and to each other in parallel.

Abstract: According to some examples, solutions are provided for power distribution of input alternating current (AC) power to at least one power outlet while the input AC power is available, charging of a set of batteries by the input AC power while the input AC power is available, and power distribution of direct current (DC) power from the set of batteries to the power outlet when the input AC power is not available. For such examples, the power outlet is capable of conducting AC power and DC power to a load that is coupled to the power outlet and that can receive either AC power or DC power.

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: An apparatus includes a plurality of energy storage modules (ESMs) to store charge. Each ESM includes module inputs to receive the charge. A plurality of charging circuits supply electrical energy to charge the ESMs via an output from each of the charging circuits. A switch network selectively switches each of the outputs from each of the charging circuits to the respective module inputs of each of the ESMs in response to a control command.

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.

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: An uninterruptible power supply (UPS) includes a first battery set and a second battery set. The UPS includes a charging circuit to charge the battery sets using alternating current (AC) power. The UPS includes a slot receptive to insertion of different types of output modules that each include an inverter to convert direct current (DC) power from the first and second battery sets, including a first type that connects the first and second battery sets in parallel and a second type that connects the battery first and second sets in series.
