WebMar 22, 2024 · A flyback transformer works by storing energy in a magnetic field and then releasing it in a controlled manner. When a DC voltage is applied to the primary winding of the transformer, it creates a magnetic field. This magnetic field then stores energy in the transformer’s core. 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 which is available in its magnetic circuit. This can be exploited using extra windings to provide power to operate other p…
