ABSTRACT:
An ignition system for an internal combustion engine capable of starting the engine even when a battery voltage is insufficient for ignition. A secondary voltage feedback circuit connected to a secondary winding of a transformer constituting a part of a DC--DC converter rectifies a secondary voltage of polarity opposite to that of the voltage applied to an ignition capacitor. The rectified voltage is fed back to the output side of the battery to compensate for lowering of voltage supplied to an ignition control circuit (10) from the battery (3).
