BASIC APPLICATION
The applications of the lighter using the capaci-
tance discharge topology operate in 2 phases :
PHASE 1
The energy coming from the mains is stored into
thecapacitor C.Forthat, theAC voltageis rectified
by the diode Ds.
PHASE 2
At the end of the phase 1, the voltage across the
capacitor C reaches the avalanche threshold of
the zener. Then a current flowsthrough the gate of
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 current flow through C,
D and the primaty of the HV transformer.
The maximum Rs value is equal to :

COMPONENT CHOICE
RS RESISTOR CALCULATION
The Rs resistor allows, in addition with the capacitor C, to adjust the spark frequency and to limit the
current from themains. Itsvalue shall allow the thyristor Th tofire even in worst case conditions. In this
borderline case, the system must firewith the lowest value of RMS mains voltage while the breakdown
voltage and current of the FLC are at the maximum.
