Talk:Flyback converter

message: In multiple places, this article says the Flyback Converter is an isolated version of a Boost Converter, which is false. The Flyback Converter operating in CCM has the same voltage transfer ratio as a Buck-Boost converter, scaled by the transformer turns ratio.  — Preceding unsigned comment added by 2610:48:100:8DA:608E:3198:92FD:84FF (talk) 13:55, 31 March 2014 (UTC)
thread_title: Isolated What?

message: "The Voltage feedback loop requires a lower bandwidth due to a zero in the response of the converter."  Can it be phrased more clearly? --Treekids 05:41, 1 December 2007 (UTC)
thread_title: What does this mean?

message: Why not a short sentence in the introduction which states this? It may be obvious to an electronic engineer, but most readers are not electronic engineers.Landroo (talk) 15:39, 1 January 2010 (UTC)
thread_title:  What is the purpose of this circuit? 

message: The text says "The voltage across the secondary winding is negative, so the diode is reverse-biased (i.e., blocked)".
I don't think that saying "blocked" is proper. I would rather say "open". Yes, a regular reverse-biased diode will block current but in this specific context it doesn't sound good.

thread_title:  Improper phrasing 

message: The flyback is not like a buck boost converter. It's like a BOOST converter. Check the respective articles and compare the schematics. The flyback is like a boost converter with a secondary winding added to the inductor.
:No, the flyback is the same as the "inverting buck-boost" coverter with the inductor split into a transformer. One thing that does make the comparision a little more confusing when looking at the wikipedia schematic is that they have drawn the flyback with the in-phase ends of the transformer at opposite ends. So the direction of current round the output side is opposite, not becuase of any physical difference in the circuit but simply because of how the transformer is drawn.

thread_title:  not like a buck-boost converter 

message: "... although the output voltages have to be able to match each other through the turns ratio." Factually wrong, because it confuses "turns ratio" with "turns-per-volt ratio". The turns ratio of a transformer is the ratio of secondary to primary turns. The outputs of a multiple-output flyback transformer *don't* have to "match each other", least of all "through the turns ratio." On the contrary: in the general case outputs can have different voltages, which requires that the turns ratios *do not match*. What must match is the turns-per-volt ratio; it must be the same for each output winding.  — Preceding unsigned comment added by 47.72.123.155 (talk) 08:16, 30 August 2015 (UTC)
thread_title:  Output voltages needn't match each other 

message: The term 'flyback' probably originated because the high voltage pulse that
charges the CRT capacitance is generated by the collapse of the magnetic
field in the core of the transformer during the short retrace period - when
the electron beam in the CRT 'flies back' to the start of a new scan line.
