<p>In an ignition device (3), in particular for an externally ignited internal combustion engine, the passage of current through the primary winding (1a) of an ignition transformer (1) is controlled by a current control device consisting of a preliminary stage (3a) and a final stage (3c). The final stage (3c) of the current control device comprises a pnp transistor (T100), the collector terminal of which is connected directly to the earth terminal of the ignition device in order to improve the output of the loss line. Decoupling means (3b) which protect the preliminary stage (3a) from the holding voltage are arranged between the preliminary stage (3a) and the final stage (3c).</p> |
