If I may so suggest -- I believe you need to do =a lot= more
basic study before attempting practical high-voltage work of
any kind:
For all ordinary purposes, every transformer that ever there
was is an =ac= operated device. Hence, your request is a
contradiction in terms.
For the sake of completeness -- there are
transformers intended to transform pulsating
dc. Such however are rare items and rather
inefficient at best. The pulsating dc is
equivalent to an ac wave riding atop a dc bias.
Only the ac component is transformed. The dc
component only serves to saturate the trans-
former core, greatly reducing overall efficiency.

P.S.: Perhaps you mean an induction coil? By a proper
stretch of the imagination, these could be considered
as pulsating dc high-voltage "transformers". Induction
coils are very readily available from manufacturers and
distributors of scientific apparatus for schools. See
"Thomas' Register of Manufacturers" under "scientific
apparatus". They are =not= inexpensive by any
measure although one should last your entire lifetime.
