Abstract
A DC current path for DC power transmission includes a switchable element. An inductance is connected in series to the switchable element. When an interrupt scenario is detected, a resonance circuit is connected in parallel to the series connection of the switchable element and the inductance for charging a capacitance of the resonance circuit. An open state of the switchable element is effected and the resonance circuit is connected in parallel to the switchable element. By means of such arrangement and method, favorable fast interrupt times can be achieved.
