Abstract
The present disclosure relates to a high voltage bypass device, comprising a cavity, a trigger element arranged in the cavity, a reservoir filled with a conductive, flowable material, and a shutter separating the cavity and the reservoir. The trigger element is connected to a first terminal and a second terminal of the high voltage bypass device. The shutter is configured to open a passage between the cavity and the reservoir in case the trigger element is triggered by an overvoltage condition, such that the conductive, flowable material at least partially fills the cavity, thereby forming a conductive path from the first terminal to the second terminal. The present disclosure further relates to a voltage source converter (VSC), in particular a modular multi-cell converter, and an operating method for a high voltage bypass device.
