Abstract: Example implementations relate to plug-in backup energy devices. In some examples, a plug-in backup energy device may comprise a charger, an energy storage device coupled to the charger, and a buck-boost converter coupled to the charger and the energy storage device such that the buck-boost converter maintains a charge of the energy storage device during a no-fault mode of a computing device, and in response to the plug-in backup energy device switching from a normal mode to a power supply mode as a result of the computing device experiencing a fault, regulates a voltage output of the energy storage device to provide energy to the computing device during the fault of the computing device.

Abstract: Example implementations relate to performance tests of capacitors. In some examples, a controller may comprise a processing resource to measure a change in voltage of a capacitor of a circuit in response to the controller entering a test mode, determine, based on the measured change in the voltage and an impedance of the circuit, a capacitance of the capacitor, compare the determined capacitance of the capacitor to a predetermined capacitance value, and determine, based on the comparison, a performance of the capacitor.

Abstract: In some examples, a controller may include a processing resource and a memory resource storing machine readable instructions executable to cause the processing resource to set an electrical power threshold, monitor an amount of electrical power distributed between a plurality of phases of a multi-phase converter operation. The controller may detect a load disparity between a particular phase of the plurality of phases, disable the particular phase, and redistribute the electrical power amongst the remaining phases of the multi-phase converter operation.

Abstract: Inductors are described herein. In one example, an inductor can include a first lead positioned on a first side of the inductor to couple the inductor to a first circuit that includes a power supply for a second circuit, and a second lead positioned on a second side of the inductor to couple the inductor to the second circuit to provide electrical power from the power supply to electrical components coupled to the second circuit.
