There is provided an electrical system, comprising: a DC source configured to provide a DC electrical power; a bus electrically coupled to the DC source, the bus comprising a load, a DC-DC converter having an input side and an output side; a switching arrangement electrically coupled to the DC-DC converter, the DC source and the bus; and a control system. The input side of the DC-DC converter is configured to receive a fraction of the DC electrical power provided by the DC source. The fraction is less than unity. The control system is configured to operate the switching arrangement to selectively configure the electrical system, in at least one of a voltage increase mode and a voltage decrease mode.
