Striking pulse
1/ THE AC POWER SWITCH: FUNCTIONAL DESCRIPTION
The Starter is a bi-directional switch which performs two functions:
the preheat of the tube,
the ignition of the tube.
During the preheat period, the ASD
is fully
conducting. The tube lamp is short circuited by the
starter, and the current flows through its filaments. In
these conditions, the tube can not light up, but the
temperature of the tube electrodes increases.
At the end of the preheat period, the lamp filaments are
warm enough to emit electrons in the gas and to permit
the lamp ignition in good conditions. The ASD switches
off the preheating current . At this moment, the ballast is
equivalent to a current generator (I=ISO, ISO = Switched
Off current). As the ASD switches off, the starter voltage
increases. The amplitude of this high voltage spike is
clamped by the ASD (VBR≈1350 V). As the starter and
the tube are in parallel, the striking pulse is directly
applied to the tube. The electromagnetic energy of the
ballast is then discharged through the tube and the
ASD.
2/ WHAT’S NEW IN THIS SWITCH?
The AC SWITCH merges an auxiliary power supply for
the driver, a power clamping device (1350V) and a
bi-directional switch with his execution pilot block.
