An internal-combustion engine ignition system comprises a power source with a voltage stabilizer; a compacitor connected to the power source through a rectifier; several circuits connected in parallel with the capacitor and ignition coil primary windings and thyristors. To the control gate of each of the thyristors is connected a control circuit with a control pulse generator. Also connected to the thyristor control gates is an arrangement for applying a negative bias to the control gates. This arrangement is in the form of a diode whose anode is connected to the cathode of each of the thyristors, whereas the cathode of said diode is connected to the capacitor and is also connected through isolation diodes to the control gate of each of the thyristors.
