Abstract
An ignition system for an internal combustion system has a power source for passing a DC voltage, a push-pull isolating transformer connected to the power source so as to increase the voltage from the power source and convert the DC voltage to AC voltage, a high-voltage transformer having a primary winding connected to an output of the push-pull isolating transformer, and a spark plug connected to a secondary winding of the high-voltage transformer. The high-voltage transformer increases the voltage from the push-pull isolating transformer to a voltage that fires the spark plug.
