Abstract:
A convener cell includes first and second arms, each of which includes a semiconductor switching element and a diode, and a short circuit part connected in parallel to the second arm, and when a DC fault detection unit detects occurrence of a DC fault, a control circuit outputs, to the converter cell, a fault handling command for setting the short circuit part to a conductive state, setting the semiconductor switching element to a conductive state, and setting the semiconductor switching element to a non-conductive stale, to thereby set both the semiconductor switching element and the diode to conductive states in the second arm.

Claim (Index 11):
A power convener, which is configured  10  interconnect an AC system and a DC system to transfer electric power, the power convener comprising,\n a plurality of converter cells connected in series to one another; \n a DC fault detector to defect a fault that has occurred in the DC system; and \n a controller to control each of the plurality of convener cells, \n wherein each of the plurality of convener cells includes;\n a first arm which includes a first semiconductor switching element and a first diode; \n a second arm, which is connected in series to the first arm, and includes a second semiconductor switching element and a second diode; \n output terminals connected to both ends of the second arm; and \n a short circuit switch formed of a mechanical switch and connected in parallel to the second arm, \n wherein the controller is configured to output, when the DC fault detector detects the occurrence of the fault, a fault handling command to each of the plurality of converter cells, and \n wherein the fault handling command is configured to set the first semiconductor switching element to a non-conductive state, set the second semiconductor switching element to a conductive state, and set the short circuit switch to a conductive state, \n \n wherein, in response to the fault handling command output by the controller, response time until the second semiconductor switching element is set to the conductive state is configured to be longer than response time until the first semiconductor switching element is set to the non-conductive state.
