Ignition circuit for supplying power to ignition electrode such as for igniting gas flame, comprises transistor connected to RC circuit which is connected to middle terminal of voltage divider

摘要

The ignition circuit has a transformer whose primary coil can be controlled by a pulse generator circuit. The ignition electrode is connected to the secondary coil of the transformer, and has a capacitor connected to the primary coil. The capacitor is charged via a thyristor.The thyristor is connected in parallel with this series circuit and is connected to a mains terminal via a resistor and a diode. The trigger terminal of the thyristor is controlled via a transistor which is controlled by an RC circuit connected to the middle terminal of a voltage divider circuit. The transistor is connected to the capacitor of this RC circuit and is base connection is connected to the middle terminal of the voltage divider.
