Abstract
Proposed is a sub-module of a power converter, the sub-module capable of allowing failure-causing electric current to quickly bypass the sub-module when a failure occurs in the sub-module. A sub-module of a power converter according to an embodiment of the present disclosure, the sub-module including an energy storage unit, at least one power semiconductor circuit connected, in parallel, to the energy storage unit and configured with a plurality of power semiconductor switches and a plurality of freewheeling diodes, and a switching element arranged between two output terminals connected to one of one or more of the power semiconductor circuits, forced to undergo an induced failure when an induced-failure signal is input into a gate terminal thereof, and internally short-circuited, thereby connecting the output terminals to each other.
