ABSTRACT:
A pulse generating circuit is provided by charging from a DC power source through charging resistor to a capacitor; detecting the preset value of the charging condition of the capacitor; discharging the charge of the capacitor through a main thyristor by triggering the main thyristor and generating a pulse output to a load by the discharging current. The pulse generating circuit comprises a shunt circuit for dividing the voltage of the DC power source beside the circuit for charging the capacitor whereby the potential of the shunt point is compared with the charged voltage of the capacitor through a three terminal trigger element and the trigger element is turned on when the charged voltage of the capacitor becomes substantially equal to the voltage of the DC power source to obtain the trigger output of the main thyristor.
