<p>An auxiliary voltage, which may be in the order of ten times the value of the battery voltage in an automotive vehicle, is provided by a voltage transformer generating circuit connected to the battery, and providing an additional voltage to the primary of the ignition coil to accelerate the rate of rise of current flow therethrough and provide for reliable energy storage in the primary of the ignition coil even at high engine speeds and rapidly succeeding ignition events. The auxiliary voltage is preferably generated by an auxiliary inductance coil connected to an auxiliary switching transistor which is gated OFF when the current flow through the inductance coil has reached a predetermined value, the resulting voltage peak being transferred over a storage capacitor to the primary of the ignition coil.</p> |
