A vessel includes electric connectors for receiving one or more direct voltages from a shore-side electric power system. The vessel includes a transmitter for transmitting, to the shore-side electric power system, a control signal enabling the shore-side electric power system to control the one or more direct voltages to be suitable for the vessel. Alternatively, the vessel includes one or more controllable direct voltage converters and a control system for controlling the one or more controllable direct voltage converters to convert the one or more direct voltages into one or more direct voltages suitable for the vessel. The vessel can be for example a ship, a boat, or a ferry.

Systems and methods associated with electrical systems of aircraft are disclosed. A method disclosed herein comprises generating electricity using an electric generator operatively coupled to an engine of the aircraft, supplying the electricity generated using the electric generator to a baseline power bus; generating electricity using an electric starter generator operatively coupled to the engine; and supplying the electricity generated using the electric starter generator to a supplemental power bus independent from the baseline power bus.

This specification describes a power distribution system comprising a first section that receives power from a first source. The power at the first section is adjusted by a rectifier coupled to a power bus of the first section. The system includes a second section that is separate from the first section and that receives power from a second source. The power at the second section is adjusted by a rectifier coupled to a power bus of the second distribution section. The system includes a swing rectifier connected to each of the first and second sections. The swing rectifier is configured to provide power to the first power bus and to the second power bus and to dynamically adjust the power capacity of the first section that is available to computing loads, and to dynamically adjust the power capacity of the second section that is available to computing loads.

An power system for a power system. The power system includes multiple electrical power sources and an enclosure operatively connected to the power sources at multiple input terminals. Multiple loads operatively connect to the enclosure at multiple output terminals by multiple cables. The enclosure includes the input terminals and the output terminals and a controller unit. Multiple selection units operatively connect to the controller unit, multiple power converters are connected to multiple connection paths. The selection units connect to at least one of multiple switches connected in the connection paths. Multiple sensor units are operatively attached to the controller unit which is configured to sense multiple parameters in the connection paths. Responsive to the parameters sensed by the sensor units, the selection units select the connection paths between the electrical power sources and the loads.

Disclosed a device for the load-free disconnection of a plug-in connection, which has an electrical disconnecting device and a locking clip. The locking clip can be pivoted both into a position locking the plug-in connection and into a position unlocking the plug-in connection. The device also has a sensor system, which interacts with the locking clip in its locking position to detect the locked state, in order to control the electrical disconnecting device.
