High pulse rate ignition system

摘要

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.
