<p>The device has a rectifier (G) that is provided with alternating current by a supply unit, and a consumer load (M) that is provided direct current by the rectifier. A control device (SE) controls the consumer load according to a control signal received by the supply unit, and a common ground line (E) is provided the alternating current and the control signal from the supply unit. A substractor (S) provides different between the control signal and potential of the ground line into the control device. An independent claim is also included for a drive system with a drive equipment and a supply unit.</p> |
