Next, the operation will be described with reference to FIG. First, FIG. 2A shows the forward blocking characteristics of the thyristor, in which the anode A of the thyristor S is (+) and the cathode is
When the power supply PW is applied to the node K (-), the power supply PW has a blocking function up to a predetermined voltage, and when the voltage becomes higher than a certain voltage (VBO), it is self-ignited to be in a conductive state, indicating that the current IA flows. . When the thyristor starts to deteriorate at the place, the thyristor S shown in FIG.
