Реферат: An electronic ignition module for an internal-combustion engine that is supplied with sparking energy from a rotating magnet includes a switchable semiconductor device through which current in the primary of an ignition coil is to be conducted. A portion of a circuit in the module senses a time when voltage across the semiconductor device approaches a maximum value, and produces a signal at that time that switches the semiconductor device out of conduction. A positive-feedback circuit is connected to increase the switching speed of the semiconductor device. The semiconductor device is protected against AC voltages of a po-larity opposite to that of the conducting direction of the semiconductor device, and is caused to advance switching time in re-sponse to increased voltages associated with high engine speed. A temperature-sensitive resistor controls spark advance in a hot engine, reducing the amount of the advance to permit restart of the engine if it is stopped briefly.
