  • Inductive spark ignition for combustion engine
    Patent number: 4064415
    Abstract: An inductive spark ignition system for a gas turbine engine in which the switching semiconductor and other components are protected from failure under igniter plug load conditions. The ignition system includes means for positively turning off the switching semiconductor to start a firing cycle and for insuring that the switching semiconductor remains nonconducting long enough to dissipate the energy in the firing circuit. A Darlington transistor is used for switching and means are provided for limiting voltage and current in the transistor pair.
