摘要： PURPOSE:To accurately and rapidly detect the defect of a thyristor by sampling and storing a forward voltage detection signal outputted from a photoreceptor and checking the presence or absence of the signal when the firing signal of a thyristor is generated. CONSTITUTION:A light signal outputted from a light emitting element inserted between the anode and the cathode of a series thyristor is detected by a photoreceptor 5. The output of the photoreceptor 5 is inputted through an amplifier 21 to a memory circuit 22, sampled and stored. A detector 23 detects the defect due to the presence or absence of the forward voltage detection signal of the memory 22 when the firing signal of the thyristor is generated.

摘要： PURPOSE: To prevent the damage of a voltage suppression element by connecting the voltage suppression element and a detector which detects the forward voltage in parallel with an optical firing thyristor, thereby protecting the firing thyristor against an overvoltage or monitoring the number of elements, to which the forward voltage is applied.
CONSTITUTION: Voltage suppression elements 54∼57 are connected in parallel with optical firing thyristors 50∼53, and light emitting elements 66∼69 which generate time signals, to which the forward voltage is applied, are further connected. The output of an operational amplifier 86 for adding the voltage signals becomes a value proportional to the number of the firing thyristors, to which the voltage is forwardly applied. When the forward voltage is applied to the optically firing thyristors less than 50, the output of an AND circuit becomes "1", a signal is applied to a firing signal generator 22, a transistor 25 is operated, light emitting elements 27∼30 emits lights, and firing signals are fed to the thyristors 50∼53. Accordingly, all thyristors 50∼53 are fired, thereby eliminating the voltages at the elements 54∼57.
