DESCRIPTION

The FLC01 series has been especially developed
for capacitance discharge operation. The main
applications are gas lighters or ignitors such as
cookers / gas boilers / gas hobs...

Based on ST’s ASD™ technology, it provides a
fully integrated function, with high performance
and reliability levels, adapted to severe and hot
temperature environment.

FLC01-200x

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

PHASE 1

The energy coming from the mains is stored into
thecapacitorC.Forthat, the AC voltage isrectified
by the diode Ds.

RS RESISTOR CALCULATION

The Rs resistor allows, in addition with the capacitorC,thesparkfrequency to be adjusted and the current
from the mains to be limited. Itsvalueshall allow the thyristor Th to fire evenintheworst case. In this case
the system must fire with the lower RMS mains voltage value while the breakdown voltage and current of
the FLC are at the maximum.

PHASE 2

At the end of the phase 1, the voltage across the
capacitor C reaches the avalanche threshold of
the zener. Then a currentflowsthroughthegateof
the thyristor Th which fires.
The firing of the thyristor causes an alternating
current to flow through the capacitor C.
The positive parts of this current flow through C,
Th and the primary of the HV transformer.
The negative parts of the currentflowthroughC,D
and the primaty of the HV transformer.

The maximum Rs value is equal to :
