| [Closed] Flyback transformer testing and replacement |

OK, This isa my domb questions day... I thought a flyback transformer is that thing you find in older TVs that are ussually round like an automobile coil..(TV is a little smaller. That has 4,5, 0r 6 usually, round outlets coming out of the tops. IF that is not a flyback transformer, What on earth is it??? |
| floobydust:
That is a colour TV flyback transformer integrated with built-in rectifier diodes, and focus anode and screen voltage dividers (two potentiometers). It's all in one. |

Thanks Ian! If I were to change the title of my post to reflect what that transformer really is. So the title is more accurate for everyone how would you call what I call "flyback transformer"? |
| james_s:
"Flyback" is the topology of the power supply, a flyback transformer is one that is designed to be driven in flyback mode. While a television HV transformer is often referred to as a flyback transformer, it is not the only type. |

Thanks for all the answers! I think I understand it better now. I am now trying to understand how the current flows on the circuit and what would be the expected voltages on A and B considering I have a couple of regulators that would take up to 15v. I imagine my B should be something around 10V ac right and A around +5v DC? |
