Abstract: An example module may include a first input power connector and a second input power connector; an input power line transfer switch circuit to connect one of the first input power connector and the second input power connector to an output power connector based on a power event; and an energy storage component to connect to a hot plug output power connector.

Abstract: Examples herein relate to a power supply system for a server. The system comprises a primary source, a power interface and a direct current (DC) energy supply chargeable by the primary source through the power interface. The primary source to power the server through the power interface and in the event of failure of the primary source, the DC energy supply powers the server through the power interface. The DC energy supply is located inside the server on a cool side of the server.

Abstract: Example implementations relate to determining a failure event of a power supply. In some examples, an apparatus may comprise logic circuitry coupled to a signal line, the logic circuitry to receive a monitor signal via the signal line, where the monitor signal corresponds to an internal voltage of a power supply that is consumed wholly by the power supply, compare the monitor signal to a reference signal, and determine, based on the comparison, whether a failure event has occurred in the power supply.

Abstract: 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.

Abstract: Examples relate to power supply comprising a power source to generate an inrush current, an active inrush current control circuit that is electrically coupled between the power source and a bulk capacitor and that is to control inrush current to the bulk capacitor, and an energy storage component electrically coupled to the active inrush current control circuit that is to power the active inrush current control circuit prior to operation of the power supply.
