Patent abstract
A method for operating a device in which typically a very high current is generated when the device is turned on compared to the rated current, e.g. an analogue operated PTC heating device for a mobile device, such as a vehicle, is disclosed. In this method, the power on the device is increased in a defined limited manner or in a ramp-like manner in the connection phase to avoid a high current when the device is switched on.
