Abstract
PURPOSE:To make steady supply of a thyristor with trigger current for improving generated spark in performance by placing two monostable multi-vibrators with a mutually different frequency on the way of guiding ignition timing pulses of a thyristor trigger circuit. CONSTITUTION:A CDI-type trigger circuit generates spark through a process wherein power supply with DC12V for example is converted into DC350V by a convertor 11 and led to a condenser 13 through a choke coil 12, and the voltage charged there is applied to an ingition coil 14 by a thyristor 10. The thyristor 10 is triggered by a trigger driving circuit 9. The timing pulses generated between ultraviolet-ray diode 2 and a photo-transistor 3 is led to a trigger driving circuit 9. The charge time of the condenser 13 can be kept optimum by providing two monostable multi-vibrators 8 and 9 with a mutually different frequency in the routine leading to the circuit 9.
