Circuit arrangement and method for reducing an electric field in a vicinity of an electrical supply line

The invention relates to a circuit arrangement (1) comprising a control device (2), an electrical load (3) and an electric supply line (4) via which the control device (2) to the consumer (3) is connected. The control device (2) is adapted, provided one in the supply line (5) electrical supply voltage (U0) to switch, and thereby a time course (9) of the supply voltage (U0) to adjust. In addition to the supply line (4) has an electrical compensation line (16) is arranged, wherein connected to a first, device-side cable end with the control device (2) and a second load side conductor end (16 ') to the load (3) is open. The control device (2) has a mirror circuit (17) which is adapted in the compensation line (16) to produce a to the time course (9) of the supply voltage (U0) in such a mirrored voltage curve (18) such that a sum ( 19) of the profile (9) of the supply voltage (U0) in the supply line (4) on the one hand and of the voltage waveform (18) in the compensation line (16) on the other hand, is within a predetermined tolerance interval, and is in particular constant.
