If it drives, say, the input of a

Bad engineering can create grim outcomes. Better to not do that.

It becomes a bang-bang regulator. If the controller is to be a custom
IC, a modest amount of complexity is free, so some intelligent
zero-crossing thing would be appropriate. But just dumb bang-bang
ought to work.

From the ridiculous to the sublime to the ridiculous!

This is one variation:

inrush current will destroy it.

As I mentioned, and you snipped, people often include a series
resistor to limit transient currents.

And yet your circuit shows that some people - who should know better -
don't.


Idiot whining again. That's pretty much your skill set.

I'm the idiot???

You claim that people often include a series resistor to limit
transient currents and yet, the circuit you show - which seems to be
susceptible to damage from transients - doesn't include the resistor
you claim should be there.

I said in plain English that a series resistor might be appropriate.
In some cases, like a clean low-voltage AC source, it might not be
needed. I've done lots of voltage-doubler type supplies with no series
R.

In this instance, since you identified the input as "AC LINE" and the
thread is about mains driven current limited supplies, your
low-voltage driven doublers are irrelevant.

Also, the cleanliness of the source has very little to do with what
will happen when the mains gets switched into the load at different
angles.

All you do is whine.

Hey, the Blue Angels are buzzing the building. I'm headed for the

In response to any of _your_ posts, more than likely.
