What's the theory of self-oscillating modulator?

[xuhaoz]

Hi, all

I tried to find some explainations about self-oscillationg modulator, but there are only some simulation procedures and there is no explaination about that why it is called self-oscillationg, what's the theory there ? So could you please show me something about this? Thank you very much.

Best Regards
Jimmy

Spend more than 10 minutes searching the forum and you'll certainly find some useful information. There's even a thread on the next page you'd be interested in reading entitled " Explanation of Self Oscillating Class D". Your english is good enough that I would have thought the name "self oscillating" would be explanation enough.

Yes, I have already read that post and the link article. I totally don't understand.

That article didn't told us what is self-oscillating modulator? why the parameters can be set like that?

For a beginner , Could you please explain it a little bit more clearly ? Thank you verymuch.

I found Bruno's AES paper a useful document

I googled and found tons of information about class d, from concept to application in details. No worries, informations are very cheap today. What you shall do just catch them.
