Abstract
In a multilevel converter, three switches are connected between three arms and three reactors, and three resistive elements are connected to the respective three switches in parallel. The three switches are configured to be in a conductive state during a normal operation. The three switches are configured to come into a non-conductive state when a short circuit accident occurs between two DC power transmission lines, whereby an inter-arm direct current flowing in four arms and the like is quickly attenuated by the three resistive elements.
