Abstract
In a multilevel converter, three circuit breakers are respectively connected between three arms and three reactors. One circuit breaker is a DC circuit breaker configured to interrupt direct current when a short circuit accident occurs between two DC power transmission lines. Each of the two circuit breakers is an AC circuit breaker configured to interrupt alternating current when the short circuit accident occurs. When the short circuit accident occurs, the two AC circuit breakers are brought into the non-conductive state and then the DC circuit breaker is brought into the non-conductive state, thereby interrupting the short circuit current.
