Hybrid ignition circuit for an internal combustion engine

摘要

An ignition circuit for an internal combustion engine. The ignition circuit includes a transformer having a secondary winding for generating a spark and having first and second primary windings, a capacitor connected to the first primary winding to provide a high energy capacitive discharge voltage to the transformer, a voltage generator connected to the second primary winding for generating an alternating current voltage, and a control circuit connected to the capacitor and to the voltage generator for providing control signals to discharge the high energy capacitive discharge voltage to the first primary winding and for providing control signals to the voltage generator to generate the alternating current voltage.
