Talk:Flyback diode

From Wikipedia, the free encyclopedia

First page created in wikipedia! (Done some minor edits and corrections before, though)

Not great with diagrams. Stuck these in here (I think they're right) in the hopes that someone might come up with something better down the road.

This isn't a complete definition either, just one that can act as a starting point for a more elaborate treatment.

Hello Ryansturmer, I hav created an new drawing, which eliminates some errors in the former diagrams. Unfortunately it is an jpg. Feel free to create a better one (svg, png) from it to add it to your good explanation.--Ulfbastel 09:40, 5 September 2007 (UTC)

Dear Ulfbastel, thank you very much for improving this article.

Would it help (or just make things more confusing?) to graph *both* the voltage across the switch, *and* the voltage across the inductor? The 2 voltage graphs are very different from each other, causing many people to jump to the incorrect conclusion that one or the other "has errors". Perhaps it would be educational to point out that both are right.

The voltage spike across the switch (not the voltage spike across inductor) is usually the biggest problem in real circuits. So if you decide to draw only one voltage graph, this is the one I would prefer. Many transistor switches come with a built-in diode. Too often people incorrectly believe that diode can be used as the flyback diode in this kind of circuit. The "voltage across the switch" graph is the only one that clearly shows why they need *another* diode.

The graph of the voltage across the switch, on the other hand, is always positive.

The figures in this article are wrong. when the switch opens, the voltage at point B will go largely positive, which means that the voltage in your chart should go largely negative! --Gabe Brisson —Preceding unsigned comment added by 63.251.211.5 (talk) 23:54, 17 April 2008 (UTC)

[edit] Merge with Free Wheeling Diode

I think those articles are just about the same thing, whereas this one is a little bit more elaborate. --sdschulze (talk) 16:32, 12 May 2008 (UTC)
