In a flyback transformer, the primary winding need not be excited by ac voltage but can be excited even with a dc pulse input. The dc pulse input can be of low rating like 5 v or 12 v, which can be obtained even from a function generator. The dc voltage is converted to dc pulse with a rectifying circuit.
A transformer is an electrical device which, by the principles of electromagnetic induction, transfers electrical energy from one electric circuit to another, without changing the frequency. The energy transfer usually takes place with a change of voltage and current.

A transformer changes the voltage level (or current level) on its input winding to another value on its output winding using a magnetic field. A transformer consists of two electrically isolated coils and operates on faraday’s principal of “mutual induction”, in which an emf is induced in the transformers secondary coil by the magnetic flux generated by the voltages and currents flowing in the primary coil winding.
