ABSTRACT:
A pulse is generated in an output transformer and this pulse is used to provide a spark across a spark gap for the purpose of igniting any gas/air mixture present. The circuit operates from a 1.5 volt d.c. source.
A blocking oscillator is energized by a two position switch which is operated to a first position, and this charges a capacitor. The capacitor is then discharged through an output transformer to produce the spark when the switch is returned to its original rest position. The winding used to charge the capacitor from the blocking oscillator is also used in the discharge path for the capacitor and this inductive loading provides a slower discharge and a more controlled lower energy spark which is found to be better for gas ignition.
