1. a supply unit, is characterized in that, possesses:

  • Electric power conversion unit, has the 1st thyristor of more than 1, carries out alternating electromotive force being transformed to the changer actions of direct current power or direct current power being transformed to the inverter action of alternating electromotive force;

    Heating electric hinders, for heating described 1st thyristor;

    2nd thyristor, controls the conducting of this heating electric resistance;

    Temperature detecting unit, detects temperature or the outside air temperature of the radiator arranged in order to the heat radiation of described 1st thyristor;

    AndControl unit, the temperature using described temperature detecting unit to detect, generates the drive singal described 1st thyristor and described 2nd thyristor being carried out on/off control.
