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.

Abstract: An electrical choke has a magnetic core with a distributed gap. The magnetic core is composed of an iron based, rapidly solidified metallic alloy. The distributed gap configuration is produced by an annealing treatment which causes partial crystallization of the amorphous alloy. As a result of the annealing treatment, the magnetic core exhibits permeability in the range of 100 to 400, low core loss (i.e. less than 70 W/Kg at 100 kHz and 0.1T) and excellent DC bias behavior (at least 40% of the initial permeability is maintained at a DC bias field of 3980 A/m or 50 Oe).

Abstract: An electrical choke comprises a magnetic amorphous metal core having, in combination, a distributed gap and a discrete gap. The amorphous metal is an iron based, rapidly solidified alloy. The distributed gap configuration is achieved by subjecting the magnetic core to a heat treatment, causing partial crystallization of the amorphous alloy. Such partial volume crystallization reduces the permeability of the magnetic core from several thousands to a value ranging from 200 to 800. The discrete gap is introduced by cutting the core and inserting a spacer. Depending on the width of the gap and the value of the annealed permeability, effective permeabilities in the range of 200 to 40 can be achieved. Advantageously, the reduced permeability magnetic core maintains its initial permeability under DC bias field excitation and exhibits low core loss, making it especially suited for use in power factor correction applications.
