  • Patent number: 6112730
    Abstract: An ignition system for an internal combustion engine having a transformer with a primary winding adapted to be connected to a power supply and a secondary winding adapted to be connected to a spark plug of the internal combustion engine, and a controller interconnected to the transformer so as to activate and deactivate the output of the transformer. The transformer serves to produce an output from the secondary winding having a frequency of between 1 KHz and 100 KHz and a voltage of at least 20 kilovolts. In particular, the transformer produces an output of an alternating current having a high voltage sine wave reaching at least 20 kilovolts. A voltage regulator is connected to the power supply and to the transformer so as to provide a constant DC voltage input to the transformer. The transformer produces power of constant wattage from the output of the secondary winding during the activation by the controller.
