Abstract

PURPOSE: To positively detect the abnormality of the ignition of thyristor transducers connected in antiparallel shapes, by comparing the output of a time set circuit, which obtains output wave-forms corresponding to the case of normalcy, and the output of the output current detecting circuits of the thyristor transducers by means of the thyristor transducers.
CONSTITUTION: Thyristor transducers 24, 25 connected in antiparallel shapes compare the output of a time set circuit, which gains output wave-forms corresponding to the case of normalcy, and the output of the output current detecting circuits 281, 282 of the thyristor transducers 24, 25 on the basis of the output of a current change-over control circuit 50 of the thyristor transducers 24, 25. The change of the gate pulses or thyristor elements of the thyristor transducers 24, 25 into abnormality is judged even if the time width of the output of the current detecting circuits 281, 282 is longer or shorter than the output of the time set circuit, and the action of the thyristor transducers is stopped. Thus, the abnormality of ignition can positively be detected, and the thyristor transducers 24, 25 are not operated under unsound ignition conditions.
