電停止制御装置。The current of the DC type system connected via the first converter that converts the first and second AC buses forward, the DC wire, and the second converter that converts the reverse is gradually reduced by a stop command to stop power transmission. In the power transmission stop control device, a first control circuit outputs a command to gate shift the first converter when the current in the direct transmission line reaches a first constant value due to the stop command; and a second control circuit that outputs a command to gate shift the second converter when the current reaches a second constant value smaller than the first constant value due to the stop command. A power transmission stop control device characterized by:
