Abstract:
A device (1) has a series circuit of submodules with a power semiconductor circuit and an energy accumulator connected in parallel with the power semiconductor circuit. Each submodule is associated with a short circuit device for shorting the submodule. The short circuit device is a vacuum switching tube. The device is cost-effective and at the same time enables safe bridging of a defective submodule.
