Abstract
The invention relates to an apparatus for providing capacitor charging and triggering in so-called electronic ignition systems comprising flywheel magnetos with a plurality of poles. The triggering pulses are arranged phase-shifted in time in relation to the charging pulses, whereby charging the capacitor in question is prevented after triggering initiating ignition. By arranging three windings, for example, connected in series on three adjacent magnetic core legs as capacitor charging pulse generating windings, and bridging over three adjacent ones with a rectifier with a polarity for passing through negative half pulses, a rather constant charging voltage is obtained for a wide range of the engine rpm.
