Examples of the disclosure include an uninterruptible power supply comprising an input configured to be coupled to a power source, an output configured to output power to a load, a main controller, a main logic power supply, an auxiliary logic power supply, and an auxiliary controller configured to receive power from the auxiliary logic power supply, the auxiliary controller being configured to receive a signal indicating that the load is not powered by the uninterruptible power supply, output a first signal to initiate shutdown of the main controller and the main logic power supply, and output a second signal to power-up the main controller and the main logic power supply after a predetermined period of time elapses after outputting the first signal.

An electronic apparatus includes a first component and a second component. The first component is configured to connect to a processing device containing a power storage module, and the second component is configured to connect to an extension device. In a first state, the electronic apparatus connects to the processing device and the expansion device. An external power supply provides power to the processing device through the first component, and provides power to the expansion device. In a second state, the electronic apparatus connects to the processing device and the expansion device. In response to the external power supply being cut off, power is supplied to the expansion device through the second component. The processing device is powered by its power storage module. After the electronic apparatus switches from the first state to the second state, the connection state of the expansion device and the processing device is capable of being maintained.

The present disclosure includes a system including a power supply unit that provides an output power and a supply status indicating whether the power supply unit is receiving input power. An electronic circuit is coupled to the power supply unit to receive the output power and a standby control circuit controls turning on and off the power supply unit. A power harvesting circuit generates standby power from the supply status and provides the standby power to power the standby control circuit.

A reverse power connection preventing circuit includes a diode and an actuation unit that are connected in series between a positive input terminal and a negative input terminal of a circuit breaker. A positive electrode of the diode points to the negative input terminal of the circuit breaker, and a negative electrode of the diode points to the positive input terminal of the circuit breaker. When a power supply is forward connected to the circuit breaker, the diode is cut off, there is no current on the actuation unit, and the reverse power connection preventing circuit is in a power-off state. When the power supply is reversely connected to the circuit breaker, the diode conducts, and the actuation unit is configured to prevent closing of the circuit breaker, and/or the actuation unit is configured to perform an alarm prompt, to perform an early warning.

This application provides a power supply system. The power supply system includes first switch module, an UPS, and a plurality of power consumption branches. An input end of the first switch module is connected to a plurality of power supply apparatuses. An output end of the first switch module is connected to an input end of the UPS. The first switch module is switched between the plurality of power supply apparatuses to supply power to the UPS. An output end of the UPS is connected to each power consumption branch. The UPS is configured to receive electric energy and input a first voltage to each power consumption branch. Each power consumption branch includes a first transformer module and at least one power consumption load. The first transformer module is configured to convert the first voltage into a second voltage, and then provide the second voltage to the power consumption load.

Described are mechanisms and methods to facilitate power saving in Type-C connectors. Some embodiments may comprise an interface to a Configuration Channel (CC) signal path and to a ground signal path of a Universal Serial Bus (USB) Type-C connector port, a first circuitry, and a second circuitry. The first circuitry may be operable to place toggled values on the CC signal path. The second circuitry may be operable to couple the ground signal path to a detection signal path. The placement of the toggled values on the CC signal path is enabled when the detection signal path carries a first value that corresponds with the USB Type-C connector port being connected to a USB Type-C device, and may be disabled when the detection signal path carries a second value that corresponds with the USB Type-C connector port not being connected to a USB Type-C device.
