Editing Flyback transformer (section)

==History==
The flyback transformer circuit was invented as a means of controlling the horizontal movement of the electron beam in a [[cathode-ray tube]] (CRT). Unlike conventional transformers, a flyback transformer is not fed with a signal of the same waveshape as the intended output current. A convenient side effect of such a transformer is the considerable energy that is available in its magnetic circuit. This can be exploited using extra windings to provide power to operate other parts of the equipment. In particular, very high voltages are easily obtained using relatively few turns of windings which, after [[Full Bridge Rectifier|rectification]], can provide a very high accelerating voltage for a CRT.  Many more recent applications of such a transformer dispense with the need to produce high voltages and use the device as a relatively efficient means of producing a wide range of lower voltages using a transformer that is much smaller than a conventional mains transformer.{{Citation needed|date=July 2011}}
