Abstract
The invention relates to a device for activating a control unit in a second electrical network, starting from a first electrical network in a vehicle having an electrified drive train, the first electrical network being galvanically isolated from the second electrical network, the device comprising: a signal generating module for generating a wake-up signal in the first electrical network; a transformer which is designed to transmit the wake-up signal and electrical power from a first transformer winding on the first electrical network to a second transformer winding on the second electrical network, a rectifier circuit in the second electrical network, which circuit is connected to the second transformer winding and is designed to rectify the transmitted wake-up signal, and a switching element in the second electrical network, which element is connected to the rectifier circuit and is designed to activate a control unit () when the rectified wake-up signal is present or absent at an input of the switching element ().
