Abstract: A short circuit regulating device and a modular multi-level converter comprising the same are disclosed. The short circuit regulating device according to each embodiment of the present disclosure includes an energization block energizably connected to the capacitor assembly and a shorting block contacting or spaced apart from the energization block. Each face of the energization block and the shorting block facing each other is in contact with each other or separated from each other.
The shorting block is coupled to the support portion. A cam member is rotatably coupled to the support portion, and an elastic member elastically supports the energization block and the shorting block. Therefore, contact and separation between the energization block and the shorting block can be performed by rotation of the cam member.
