Abstract
An AC circuit breaker is provided between an AC system and an AC-DC converter, and a DC circuit breaker is provided between a DC line and the AC-DC converter. A bypass switch capable of short-circuiting a converter cell included in the AC-DC converter is connected to the AC-DC converter. At the time of a fault in the DC line, the bypass switch is turned on to interrupt the supply of DC power from the AC system to the DC line.
