Before the common match the first system created
to ignite gas was the piezoelectric. However, this concept is gradually
being replaced by electronic ignition systems. Electronic ignition
spark systems use a CDI structure (Capacitive Discharge Ignition).
This system is now increasingly used in applications as varied as:
boilers, furnaces, fuel control ignition, gas ranges, insect killers,
barbecues and electric fences.
In the ignition circuit the AC mains is rectified by the
diode (Ds) and charges the capacitor (C).
When the voltage across the capacitor exceeds the threshold voltage
of the zener (Z), a current (Ic) flows into the
SCR gate. The Thyristor (Th) fires and causes an
alternating current to run through C. The positive part of this
current flows through C, Th and the primary of the transformer.
The negative part of the current runs through C, D and the primary
of the transformer. The secondary provides a high voltage (a few
tens of kilo Volts).
The FLC family of products offers customers an
efficient solution for ignition systems by proving high reliability
with more than 2 million On/Off at 120°C ambient.
Miniaturization and board space saving and component count reduction
(one instead of four) mean stocks and assembly benefits. |
