Abstract
A passive electronic fuse for protecting a DC application in the event of a fault includes a first leg including a first winding of a mutual inductor and a switch device connected in series, a second leg including a second winding of the mutual inductor. The first leg and the second leg are connected in parallel and a self-inductance of the second winding is lower than a self-inductance of the first winding. The second leg further includes a capacitor connected in series with the second winding of the mutual inductor, and the switch device is a thyristor or a switch device with switching properties of a thyristor.
