An aircraft bipolar high-voltage network includes a DC voltage converter comprising two unipolar input connections, two bipolar output connections and a reference potential connection, and at least one unipolar device having two electrical connections which are each coupled to one of the two unipolar input connections. The DC voltage converter has a first DC voltage converter module coupled to a first of the unipolar input connections via a module input connection, to the reference potential connection via a module reference potential connection and to a first of the bipolar output connections via a module output connection, and a second DC voltage converter module coupled to a second of the unipolar input connections via a module input connection, to the reference potential connection via a module reference potential connection and to a second of the bipolar output connections via a module output connection.

Bipolar high-voltage network and method for operating a bipolar high-voltage network

A DC switching device has at least one switching unit which is arranged between two terminals. Further, the DC switching device has a control unit for controlling the at least one switching unit. The switching unit has a first and a second semiconductor switching element, which are arranged in parallel with one another, the first switching element being a high-voltage switching element and the second switching element being a low-power-loss switching element. The switching unit is controllable by the control unit in such a way that, when the switching unit is switched off, initially the second switching element is switched to be non-conductive, and subsequently the first switching unit is switched to be non-conductive, and when the switching unit is switched on, initially the first switching element is switched to be conductive and subsequently the second switching element is switched to be conductive.

DC switching device and method of control

The embodiments relate to a switch device for an electrochemical energy store having: a film transistor device that comprises at least one organic transistor, can be mounted in a planar manner on at least one electrode of the electrochemical energy store, can be controlled by an external voltage source, and is designed in the form of a controllable electrical resistor that is connected, in series, to an internal resistor of said electrochemical energy store.

Switching device for an electrochemical energy store and energy storage system

A bipolar high-voltage network for an aircraft or spacecraft. The network includes at least one DC-DC converter having two unipolar input connections and two bipolar output connections as well as a reference potential connection, at least two fuel cell stacks which are coupled in series between the two unipolar input connections, and at least two discharge diodes, each connected in parallel with the output connections of one of the at least two fuel cell stacks. The DC-DC converter is operable selectively in a step-up converter mode of operation or a step-down converter mode of operation, as a function of an input voltage between the unipolar input connections.
