Abstract
A constant spark rate ignition exciter is disclosed which functions to store a predetermined constant amount of energy in an energy storage element of an ignition system independent of power supply variations. A first embodiment of the invention is a capacitive discharge ignition system. A second embodiment of the invention is an inductive discharge ignition system. Each embodiment produces the constant frequency ignition pulses by the counting of a predetermined count in a counter. The interval during which energy is stored in energy storage elements of the embodiments of the invention is determined by sensing the power supply potential and controlling the time interval for coupling the power supply to the energy storage element in a manner which is inversely proportional to the sensed voltage.
