Abstract
Circuit arrangement for the protection of a component, particularly a switching semiconductor, which is series connected to a voltage source via an inductor, against an overcurrent due to magnetic saturation of the inductor, a second inductor in the series circuit, which limits the overcurrent during the response time of an excess current cutoff and whose magnetizing current is roughly linear over time, at least during the unsaturated state of the first inductor, and does not exceed the maximum permissible current value for the component to be protected during the entire response time.
