| 摘要 |
The invention relates to a switching device for galvanically isolated 1:1 transmission of a direct current signal, with a transformer ( 3 ) comprising a primary coil ( 1 ) and a secondary coil ( 2 ), wherein the primary coil ( 1 ) is powered with alternating current derived from an input direct current (I 1 ) and the current induced in the secondary coil ( 2 ) is rectified, and with a correction device ( 4 ) for compensating transmission losses. To provide a DC transducer free of auxiliary energy, in which the output current is as close to equaling the input current as possible, it is proposed that the number of turns on the primary coil ( 1 ) should be greater than the number of turns on the secondary coil ( 2 ).
