Ignition systems having a series connection of a switch/inductor and a capacitor

摘要

An ignition system has several charging circuits connected to a common input circuit and controlled by a common triggering unit to fire respective igniters. The input circuit has a voltage source connected across a first capacitor, which provides the output terminals of the source. Each charging circuit has a second capacitor connected in series with one end of an inductance. A tapping of the inductance is connected to an input of the charging circuit via a diode and a thyristor, controlled by the triggering unit. The output of the charging circuit is provided by one electrode of the second capacitor and the opposite end of the inductance.
