design of high voltage transfomer for discharge lamp igniters

[kfel]

Hi,

I need to design a transformer with the following specification: -
1. It needs to generate high voltage pulses necessary for igniting a
discharge lamp. The pulse height is typically of the order of 3.5KV
and above.
2. These high voltage pulses need to be superimposed onto the input
sine wave

Any help on this would be appreciated. Thanks in advance

What's wrong with buying an igniter transformer off the shelf?

do you have a schematic already of the circuit your building?
I repair concert lighting equipment that uses discharge lamps. I can
tell you, the transformer is a ballast and the high voltage igniter
circuit basically momentarily pulse shorts the ballast transformer to
cause a high voltage spark across the lamp. once the lamp fires, the
ballast limits the current to the designed current. This operates much
the same as a florescent lamp only much higher currents. The 2nd
option is to use an electronic ballast type that the power supply
regulates the voltage and current to match the lamp. THe igiter is an
external high voltage "kicker" device.

which type are you trying to build so we can help further?

What i needed was help on designing an transformer coil for a
superimposed igniter and not a ballast to be used in series with the
discharge lamp.

Would one of these help you?
