Self Oscillating Class D. Question for the usual/unusual suspects

Is the "self-oscillating" bit what Intersil's HIP4080A app note calls "hysteresis control"?

AN9525 seems to contain pages and pages of analysis on this. I haven't read it.

Can't make any sense of it at all, but the OP probably ought to go read Peter Banandall's 1956 paper that I referrred to at

I was interested in the parallel resonant class-D oscillators, and the OP is after the series resonant variant.

Oooooooooooops!!!!!! Premature excitement. When I said I had terminated the delay line I put the terminating resistor in the wrong leg so my model was indeed bollocks.

I can go back to being unhappy again.... :-(

This is a great subject and very interesting. Some responses are trying to make a power supply out of it. I really like your presentation containing the SPICE files making it easy to follow. Your hard work is appreciated. We missed you at the summer gathering at JT place. Harry
