The method involves compensating for a voltage drop over an electrical supply line (2) which connects a load (1) to a voltage source (3) by a compensation AC voltage, and adding the compensation AC voltage to the desired constant AC voltage to determine an...

The stabilising system for use with an electrical power supply network Ä10Ü has an inductance Ä12Ü coupled to a converter Ä22Ü that has AC windings Ä24,26Ü, a rotor Ä28Ü and a DC excitation winding Ä30Ü. One of the windings connects with a conv...

The uninterrupted current supply device has a fuel cell (2) for generating current by cold oxidation of hydrogen to water in the event of failure of a primary current supply, especially a supply network, and a storage device for the hydrogen. A hydrolyzer ...
