Abstract

An ignition system has a switching transistor having an emitter-collector path connected in series with the primary winding of an ignition coil. The latter series combination is connected between voltage supply leads. A driver circuit has a control electrode and controls the conductive state of the switching transistor. An ignition breaker switch has alternating open and closed intervals in response to rotation of the engine. The breaker switch may have the undesirable property that it closes mometarily during the open interval shortly after opening of the breaker switch. A signal control circuit is connected to the ignition breaker switch and to the control electrode to make the emitter-collector path of the switching transistor conductive when the breaker switch is closed and to make it nonconductive when the breaker switch is open. An energy storage element, either the primary winding itself or a capacitor, stores energy prior to the closing of the breaker switch during an open interval of said switch, and the stored energy is used to maintain the control electrode at a potential to maintain the transistor path open irrespective of the closing of the breaker switch during an open interval of the same.
