Abstract: 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.

Abstract: A power converter comprises an inductor coil whose first pole is connected to an input terminal of the power converter, a controllable switch between the ground and a second pole of the inductor coil, a first unidirectionally conductive component providing a path for electric current from the inductor coil towards an output terminal of the power converter when the controllable switch is non-conductive, and an over-current protector at the output terminal. The power converter comprises a second unidirectionally conductive component for conducting electric current from the input terminal to the over-current protector in a fault situation where voltage at the output terminal is smaller than voltage at the input terminal. Thus, the second unidirectionally conductive component constitutes a low-inductance bypass route for fault current and enables the over-current protector to react fast to a fault situation.
