Abstract
A pair of power transistors in a push-pull connection are connected with a pair of primary coils of a transformer acting as an ignition coil. Between the neutral point of the pair of the primary coils and a power source at least one diode is connected. The paired power transistors are turned on and off with a high frequency to generate in the secondary coil of the transformer high voltage trigger pulses and substantially continuous discharge voltages which last over a long period during each ignition period.
