I'm currently looking for transformers to generate high voltage spikes (several kV) on the secondary by suddenly changing the voltage (and therefore the current) on the primary. Ideally, I'd have a transformer with a turns ratio of 1:100 or more so that the voltage induced on the primary coil doesn't damage any low voltage components.
My issue is that I have no idea of how to find an appropriate transformer for this. Specifically, most of the filter options on sites like Mouser and Digikey do not allow you to select the turns ratio. The only transformer that seems to provide the turns ratio are current sense transformers, but I don't that those are appropriate for generating high voltage spikes.
Some datasheets, such as this one*, don't even list it either.
My question is: is there another way to determine the turns ratio from the datasheet? For instance, in the datasheet above, is the turns ratio 6.3:230 (because those are the voltages given in the Electrical Specifications section)? Or, is there a different type of transformer that I should be using?
I should mention that I'm aware of this question, however, I'm not even looking for a specific turns ratio (the only requirement is that it's greater than 1:100). My design will be built around whichever transformer I get.
*I have no opinions on this product. This is just one I found while looking for transformers.
