REDUNDANT POWER SUPPLY NETWORK AND WATER VEHICLE WITH REDUNDANT POWER SUPPLY NETWORK AS ONBOARD NETWORK

A redundant power supply network includes an alternating voltage network and a first incoming-feed power converter with a first dc link and a second incoming-feed power converter with a second dc link. The first and second incoming-feed power converters are each connected on an alternating voltage side with the alternating voltage network. A first power source is connected to the first dc link and a second power source is connected to the second dc link. A mains switch is arranged between the first incoming-feed power converter and the alternating voltage network, and a dc link switch connects the first and second dc links. A connection to a terminal for an external network is arranged between the first incoming-feed power converter and the mains switch.
