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.

Concurrent alternating-current and direct-current

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.

Power distribution with batteries

An example power module includes an energy storage device, an energy storage carrier, and an electrical connector. The energy storage carrier houses the energy storage device and is removably insertable into a modular data storage slot of a computing device. The modular data storage slot has a data path and a first power path to removably couple to a data storage module. The electrical connector is to transfer energy from the energy storage device to a second power path associated with the modular data storage slot.

Space saving, modular, hot-pluggable power modules

The present disclosure provides a thermal spray alloy system that is more resistant to corrosion than conventional alloy compositions. The disclosed alloy comprises copper as the main component and also potentially nickel, tin, boron, and/or carbon as other principle elements. The alloy composition may utilize a cored wire, and an outer sheath of the cored wire may comprise unalloyed copper. The alloy has superior corrosion resistance to a wide number of corrosive materials, such as hydrogen sulfide, carbon dioxide/carbonic acid, sodium chloride/potassium chloride (salts), bio-fouling, and micro-biologicals. The alloy demonstrates superior thermal conductivity compared to nickel based alloys and stainless steels. The alloy may form an anti-corrosive coating that may be applied to any number of substrates. The disclosed alloy may be applied to a substrate in thick layers, such as between 0.100 inches and 3.0 inches, and may be used to form shapes, such as centralizers.

Corrosion resistant thermal spray alloy

In one example, a system for bypass switch control includes a controller coupled to a number of backup power modules and to a number of bypass switches that correspond to each of the number of backup power modules, wherein the controller activates a bypass switch when a corresponding backup power module is deactivated.

Bypass switch control

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.

Memory module battery backup

In one example, a system for parallel output of backup power modules includes a first backup power module coupled to an input and a first output of an enclosure, a second backup power module coupled to the input and a second output of the enclosure, wherein the second backup power module is coupled in parallel with the first backup power module, and a switch coupling the first backup power module and the first output of the enclosure to the second output of the enclosure.

Parallel output of backup power modules

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.

Uninterruptible power supply

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.

Battery charge voltage based on ambient temperature

Examples herein disclose receiving a communication indicating a number of loads supported by multiple nodes and determining an amount of power available at a backup power source. Based on the determination of the amount of power, the examples disclose delivering power to the multiple nodes from the backup power source.

Communication associated with multiple nodes for delivery of power

Example implementations relate to combined backup power. For example, a system for combined backup power can include a combined backup power supply (CBPS) coupled to a node and a plurality of loads supported by the node. The CBPS can include an uninterruptible power supply (UPS) and a backup power supply coupled to the UPS to act as redundancy for the UPS.

Combined backup power

An example system is provided herein. The system includes a fuel cell coupled to the set of electronic components. The fuel cell provides power to the set of electronic components when a set of conditions are met.

Fuel cell to power electronic components

Described are examples of back-up power apparatuses and systems including such back-up power apparatuses. An example may include a battery module, and a back-up power control module to determine a back-up power demand of a host device and selectively enable an output of power from the battery module to the host device if the battery module has a power capacity greater than the back-up power demand.

Selectively-enabling battery back-up power based on a power demand

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.
