Although possible, usually as twin coils in the shape of two Tesla 
coils back-to-back, this is uncommon. Are you sure that you are not
thinking in an induction coil?

They are flyback circuits similar to what is still used in ignition 
systems. They operate at much lower frequencies, are an older idea, and 
the input energy comes from current in the primary winding, instead of 
from voltage in the primary capacitance. Otherwise, their operation is
really similar to the operation of a Tesla coil.
