Circuit and method for interrupting a current flow in a DC current path |
摘要 |
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. |

1. A circuit arrangement for interrupting a current flow in a DC current path, comprising:
a switchable element arranged in the DC current path; a first inductance connected in series with the switchable element arranged in the DC current path; and a resonance circuit configured to be connectable in parallel to the series connection of the inductance and the switchable element by means of a first switch, and to be connectable in parallel to the switchable element without the inductance by means of a second switch. |
