ABSTRACT:
In the ignition apparatus for internal combustion engines, the internal combustion engine drives a generator and the generator charges a battery. The battery is connected to a boosting transformer which is connected with a semiconductor switch. The semiconductor switch causes a current to intermittently flow in the primary coil of the boosting transformer from the battery. An intermittence control circuit is connected between the semiconductor switch and the generator and controls the semiconductor switch to turn on and off a plurality of times per revolution of the generator in synchronism with the output of the generator. Thus, the semiconductor switch allows the transformer to generate a high voltage for ignition across the secondary coil. The intermittence control circuit includes an over-rotation preventing capacitor.
