Abstract
The present invention is an apparatus for controlling the ignition of an internal combustion engine. The present invention employs a high voltage transistor, preferably a high voltage MOSFET, to switch DC voltages on the order of 1 kV to regulate the flow of current to an input tap of a primary ignition transformer or coil. The high voltage transistor is controllable by conventional logic-level voltages produced by an ignition control module.
