SUSTAINED ARC IGNITION SYSTEM
Circuitry for maintaining an arc or spark across a spark gap for a desired length of time is described. 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. The high-voltage source is controlled by a solid state switch which is 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 include both a switch and a multivibrator if the timer is of the pulse-generating magnetic type.
