hello everyone,

I just came across this schematic and I need your help. I am not sure what T1/L1 and T2/L2 are? Are they transformers or just coils? and the values?

Thank you very much,
Thinh

 

T1 and T2 are transformers with high frequency core material, and the windings are not described at all, not even the ratios. so I would have no hope of being able to reproduce the package from this drawing. And packaging an assembly to power a mercury vapor lamp of some unknown wattage would certainly be an effort in futility. So if you can learn from this circuit that is fine, but it's operation is quite complex, because it is an electronic ballast for a mercury vapor light.
