Abstract: An ignition system for igniting fuel in a gas turbine or diesel engine is described. The system includes a magnetic core-coil assembly having a magnetic core comprising at least one tape wound toroid of ferromagnetic amorphous metal alloy, a primary winding and a secondary winding. Also included are driver electronics for applying voltage to a spark plug to cause a spark to ignite the fuel. The core-coil assembly and driver electronics are capable of operating with a rapid charge and discharge cycle to produce a high spark pulse rate. In another aspect, a magnetic core-coil assembly is disclosed which has a magnetic core comprising at least one tape wound toroid of ferromagnetic amorphous metal alloy having a permeability ranging from about 250 to 500, a primary winding for low voltage excitation and a secondary winding for high voltage output.

Abstract: A magnetic core-coil assembly generates an ignition event in a spark ignition internal combustion system having at least one combustion chamber. The assembly comprises a magnetic core of amorphous metal having a primary coil for low voltage excitation and a secondary coil for a high voltage output to be fed to a spark plug. A high voltage is generated in the secondary coil within a short period of time following excitation thereof. The assembly senses spark ignition conditions in the combustion chamber to control the ignition event. The assembly is constructed from sub-assembly parts that can be manufactured with existing machines at reasonable cost. The assembly is then potted in a housing consisting of a high temperature polymer.
