A supply-voltage-compensated contactless ignition system for internal combustion engines, which includes input transistor operable in response to an engine ignition signal so as to control the operation of a power transistor to control the energization of an ignition coil with the operating level of the input transistors being varied with variation in the supply voltage, further includes a current mirror circuit having first and second current shunt paths including first and second transistors which are connected in parallel with a voltage clamping device such that the each current path substantially the same amount of current when the supply voltage is normal and that one of the current paths shunts a current increased over that of the other in response to a rise of the supply voltage beyond a predetermined value, and includes a shunt device for shunting the increased current to the input transistors.
