IGNITION SYSTEMS AND METHODS

摘要

Known ignition systems have a capacitor charged by a voltage source and discharg ed via a switch. In the present invention the voltage source is connected across a first capacitor, and this is connected via a thyristor and a diode to a tapping of an inductance. The inductance is connected in series with one electrode of a second capacitor, the output to t he igniter being connected across the other electrode of the second capacitor and the series conn ected inductance. The system has several charging circuits including the inductance, s econd capacitor and thyristor each connected to respective igniters, the thyristors be ing connected with a common triggering unit.
