ABSTRACT:
Circuitry for maintaining an arc or spark across a spark gap for a desired length of time is disclosed. A high-voltage, direct-current (dc) source is connected in series with a secondary winding of a high voltage, step-up transformer or coil and a spark gap such as a spark plug for example. The high-voltage source may be on continuously or may be turned on and off by a control circuit such as a solid state switch which is, in turn, responsive to a timing device such as a set of ignition contact points or a magnetic pulse generator operating in synchronism with a spark ignition engine. The timing device also provides signals to a current switching circuit which interrupts current flow through a primary winding of the high-voltage coil at the prescribed time that a spark is desired at the spark gap.
The control circuit may, if desired, include both a switch and a multivibrator if the timer is of the pulse-generating magnetic type.
