DESCRIPTION

The FLC01 is a high performance planar dif-

-

fused technology adapted to high temperature
and rugged environmental conditions.

It has been developed especially for capaci-

-

tance discharge operation. The main applica­tionsare gas lighter orignitor such as :
cookers/ gasboilers/ gas hobs...

Th : Thyristorforswitching operation.
Z :Zener diode to set the thresholdvoltage.
D : Diodefor reverseconduction.
R:2kΩresistor.

The applications of the lighter using the
capacitance discharge topology operate in 2
phases:

PHASE1

The energy coming from the mains is stored into
thecapacitorC.Forthat,the AC voltageis rectified
bythe diode Ds.

PHASE2

At the end of the phase 1, the voltage across the
capacitorCreachestheavalanchethresholdofthe
zener.Thena currentflowsthroughthegate of the
thyristorTh which fires.

The firing of the thyristor causes an alternating
currentto flowthroughthe capacitorC.

RS RESISTORCALCULATION

The Rs resistor allows, in addition with the
capacitor C, to adjust the spark frequency and to
limitate the current fromthe mains. Its value shall
allow thethyristorTh to fireevenin theworstcase.
Inthisborderlinecase thesystemmustfirewiththe
lower RMS mains voltage value while the
breakdown voltage and current of the FLC are at
the maximum.
