| 摘要 |
The invention relates to an electrical apparatus (1), in particular for a vehicle, which has a primary control unit (2) for controlling and supplying the electrical apparatus (1) with energy and a secondary output unit (3) which is subordinate to the control unit (2) and is intended to output data transmitted by the control unit (2). The control unit (2) and the output unit (3) are connected to one another via a data line (5). In addition, the control unit (2) comprises an electrical filter (16) with three inductor coils (17, 18, 19) for suppressing interference signals. The inductor coils (17, 18, 19) are inductively coupled to one another in such a manner that a direction of a magnetic flux produced by a first flow of current in the first inductor coil (17) and of a magnetic flux produced by a second flow of current in the second inductor coil (18) in the main body is opposite a direction of a further magnetic flux produced by a third flow of current in the third inductor coil (19) in the main body. |
