A power arrangement and cooling system for electronic devices includes a processing unit electrically interconnected and disposed to a first side of a printed circuit board and a power converter electrically interconnected and disposed on a second side of the printed circuit board. The power converter includes a thermally conductive material layer that transfers heat generated by the power converter during operation away from the power converter toward a heatsink that is disposed adjacent the second side of the printed circuit board. Heat generated by the processing unit is absorbed by a heatsink disposed adjacent the first side of the printed circuit board. Power for the processing unit is provided, by the power converter, through a thickness of the printed circuit board.

Power arrangement and cooling system for electronic devices

A system including multiple power supplies is provided. Each of the power supplies is configured to provide a standby power to a management unit in the system through a standby output and a main power through a main output, when an input power signal has been received for the system. The system also includes a resistor configured to receive a standby signal from each of the power supplies to raise a signal voltage, wherein the standby signal is a pre-selected current. The system also includes a controller in each of the power supplies, the controller configured to raise the signal voltage to the specified value when the signal voltage is greater than a threshold, and to enable the standby power from a respective power supply to reach the management unit when the signal voltage is within the specified value. A method to use the above system for a synchronized power supply to a management unit is also provided.

Synchronized standby startup of power supplies with current injection

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

One example of a device includes a low voltage direct current (LVDC) bus and a high voltage direct current (HVDC) to LVDC converter to receive HVDC power from an enclosure and provide main LVDC power. The device includes a circuit to pass the main LVDC power to the LVDC bus while the main LVDC power is within regulation limits and to pass backup LVDC power from the enclosure to the LVDC bus in response to the main LVDC power falling outside the regulation limits.

Device having main and backup power

Examples relate to power supply system comprising a primary power supply to deliver a first power to a load and a secondary power supply that, in response to a failure in the primary power supply, is to deliver a second power to the load. The system further comprises a primary energy storage component coupled to the primary power supply that, in response to the failure in the primary power supply, is to deliver a third power to the load while the secondary power supply transitions from a lesser output power level to a greater output power level. The third power is at the same full-rated power level than the first power.

Energy storage components to power loads during transitions between power supplies

Examples herein disclose a first power supply comprising a controller to detect a condition associated with a device. The First power supply includes a converter to modify behavior of the first power supply in response to the detected condition associated with the device.

Behavior modification of a power supply in response to a detected condition

Example implementations relate to backup power communication. For example, a system for backup power communication can include a shared backup power supply coupled to a node, a plurality of loads supported by the node, and a pass-through device to support multi-master communication between the shared backup power supply and the plurality of loads.

Backup power communication

An example device in accordance with an aspect of the present disclosure includes a converter to convert an input voltage to an output voltage. The converter includes an input connector that occupies greater than one third of a frontal area of the converter.

Converters to convert input voltages to output voltages

An automatic transfer switch module includes an automatic transfer switch. The automatic transfer switch may receive a first power from a first power source and a second power from a second power source. The automatic transfer switch may selectively provide one of the first power and the second power to a power supply module.

Various examples herein disclose a system comprising a power source, multiple cards, and a power connector. The power source is mounted on multiple cards. The multiple cards each include an edge configured to fit into a memory slot. The power connector is coupled to the power source and located on a side of the multiple cards other than the edge.

Power source configuration to fit a memory slot

Plural electric power supplies are connected in parallel to an output bus. The plural supplies include a primary power supply and a redundant switching power supply. The primary power supply is configured to provide output current to a load when the primary power supply is operating normally. The redundant supply is configured to remain online while not providing output current to the load when the primary power supply is operating normally, but to begin providing output current to the load when the primary power supply is not operating normally.

Power supply system having a redundant supply that remains online while sourcing no power

A power converter () can include a switching system () to convert a direct current (DC) input voltage to an output voltage based on a switching signal having a duty-cycle. A controller () can set the duty-cycle of the switching signal, depending on the DC input voltage, to one of a substantially constant value, such that the output voltage follows the DC input voltage in a normal mode, and a value that varies inversely with respect to the DC input voltage, such that the output voltage is substantially constant in another mode.

Power converter dependent on a voltage range the input voltage resides in

A power supply system and method are disclosed. The power supply system is to generate a power signal for providing power to a device. The power supply system includes a transmitter to modulate a data signal onto the power signal that is demodulated at the device. The transmitter is further to transmit a separate binary control signal on the power signal to change a state of a digital control parameter associated with the device.

Data and digital control communication over power

A switching power supply includes power factor correction circuitry and a standby output converter. One or more loads may be coupled to one or more outputs of the switching power supply. The switching power supply is configured to disable the power factor correction circuitry under some load conditions and to enable the power factor correction circuitry under other load conditions. As a consequence, power that would have been drawn by the power factor correction circuitry is conserved when the power factor correction circuitry is disabled.
