  • Patent number: 4005694
    Abstract: An internal combustion engine ignition device of the capacitive discharge type which utilizes a single transistor, semi-conductive controlled rectifier and attendant reactive circuitry to provide timed high voltage application to create a direct current arc, or plasma, at the spark discharge devices. The circuit is actuated by closure of the contact points to energize a transistor to operate in a Class D amplifier mode that, in turn, enables conduction through the primary of a transformer, the secondary of which places increased voltage charge on a capacitor to a predetermined charge level. Thereafter, opening of the contact points causes conduction of the semi-conductive controlled rectifier which allows discharge of the charged capacitor through a current steering bridge to the ignition coil to enable application of high voltage for establishing a direct current arc, or plasma, at the spark discharge device.
