The first power conversion unit is a converter in which arms consisting of thyristors are connected in a bridge configuration. The second power conversion unit is an inverter in which arms each of a series combination of a thyristor and a self-excited switch unit having a GTO for producing a commutation voltage for the thyristor are connected in a bridge configuration.
