Abstract:
1. An electrical circuit to limit the switching-on current through a load during a switching-on process, comprising: a transistor with an input connected to the load, an output and a control terminal, the transistor having an internal resistance; and a timing element, which controls the transistor to reduce the internal resistance during the switching-on process, wherein the timing element includes a capacitor and a first ohmic resistor, via which the capacitor is charged, and wherein a first terminal of the capacitor is connected to the input of the transistor, a second terminal of the capacitor is connected to a first terminal of the first ohmic resistor, the second terminal of the capacitor is connected to a first terminal of a second ohmic resistor, and a second terminal of the second ohmic resistor is connected to the control terminal of the transistor.
