| 摘要 |
The invention concerns a method for controlling a direct voltage source with a first direct voltage source ( 2 ) and a voltage monitoring device ( 24 ), which monitors an output voltage of the first direct voltage source ( 2 ) and acts upon a control device ( 31 ), the control device ( 31 ) controlling the working state of the first direct voltage source ( 2 ). Further, the invention concerns a voltage supply device ( 22 ) with which the method can be used. In this connection it is endeavoured to reduce the risk of an increase in voltage in a circuit with several direct voltage sources. For this purpose, a second direct voltage source ( 3 ) produces a voltage change at the voltage monitoring device ( 24 ).
