What is a flyback transformer?
The flyback transformer (FBT), also called a line output transformer (LOPT), is a special transformer that is used to generate high voltage signals at a relatively high frequency. It was invented to control the horizontal movement of the electron beam in a cathode ray tube (CRT).
