ABSTRACT:
Two closed circuits respectively are each comprised of a primary coil of a transformer for plug ignition, a transistor, a diode, a resistor and a common power source. When one of the transistors is conductive during the ignition period, the current in the related closed circuit increases. When the increased current appearing across the associated resistor exceeds a reference value, the associated comparator renders the conducting transistor nonconductive while it renders the other nonconductive transistor conductive, whereby the transistors continues a push-pull operation at given periods. Each diode is inserted either between the associated primary coil and the associated transistor or between the associated primary coil and the common power source.
