Abstract
A DC voltage network includes at least three energy storage networks, each having an energy store supplying a DC voltage, and at least three power converters implemented as DC voltage converters. The energy store and the power converters are electrically connected at a common point, At least three DC voltage sub-networks are each connected to a respective power converter of the energy storage networks. A feed device connects a respective DC voltage sub-network to an AC voltage network. The DC voltage network may be installed in a vehicle, in particular a ship. In a method of controlling the DC voltage network in the event of a fault, at least one of the power converters is switched off to protect the DC voltage network, depending on the location of the fault.
