Abstract
During the negative half cycle of the magneto output voltage, a capacitor in series with a diode is charged to a voltage limited by a Zener diode of a negative limiting circuit. During the next positive half cycle the sum of the magneto voltage and the capacitor voltage are applied over a current limiting resistor to the base of a power transistor in the primary circuit, holding the latter turned on until a timing pulse applied to a control transistor short circuits the base-emitter path of the power transistor, switching off the latter and permitting the capacitor to discharge. The interruption of the primary current produces a spark in the secondary circuit, the armature of the magneto being wound to serve also as an ignition coil.
