practical example

can anyone give me a practical circuit of a switched mode power supply using a flyback converter....

See datasheets from national semi, IRF, texas instumenets, maxim-ic, and others. They have typical applications in the datasheets and in the application notes.

Isolated What?

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)[reply]

The output voltage is "isolated" from he input voltage...by the transformer. — Preceding unsigned comment added by 67.249.246.183 (talk) 19:26, 27 September 2014 (UTC)[reply]

Operating Mode

the operation section seems to be incorrect. in both CCM and DCM, the converter can make use of either secondary or aux feedback. the "cross regulation" of the coupled inductor design is the main difference. both provide voltage feedback. I beleive a better section would be in respect to CMC vs VMC, as many controllers are designed with respect to CMC or VMC. I will change it as appropriate

What does this mean?

"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)[reply]

What is the purpose of this circuit?

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)[reply]

Improper phrasing

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.

I would say does not conduct. — Preceding unsigned comment added by 67.249.246.183 (talk) 19:29, 27 September 2014 (UTC)[reply]

not like a buck-boost converter

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.

Flyback

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. http://www.repairfaq.org/REPAIR/F_flytest.html#FLYTEST_007
