ABSTRACT:
This application discloses a solid state ignition system of the inductive type and includes a trigger coil and an ignition coil having primary and secondary windings disposed on a stator core. A flux generating magnet is carried by a rotor to induce voltages in the coils. A Darlington transistor is disposed in circuit with the primary winding of the ignition coil with the collector emitter electrodes of the transistor connected to carry current generated in the primary of the ignition coil. The base of the transistor is connected to receive current pulses generated in the trigger coil. A parallel capacitor and resistor network is connected in circuit between the trigger coil and the base of the Darlington transistor. The capacitance of said capacitor and the resistance of the resistor are selected so that the retard angle of said system from low-to-high rotational speed of the flux generating magnet remains essentially constant.
