Abstract

Conventional automotive ignition systems comprise a high voltage Darlington bipolar transistor that switch- es an ignition coil's current for igniting the internal combustion engine gasoline air fuel mixture. However, the use of the bipolar transistor results in a substantial power loss that severely effects the heat dissipation, and therefore operation, of the system.
