And you could not solve that with judicious use of inductance and
capcitance?

Idiots that do not make power supplies always think the world can be
stuffed into a predefined chassis size.

Get a clue, dipshit. They are called design constraints. Of course
the supply had filtration in it. It is the best we could pack in that
size package, and we beat the shit out of the competing product's
specs.

Again, you know nothing about which you spew.

Cursing at me results in my disbelief in you having any ability, and proves
a serious lack of maturity. Save it for some ten-year-old you can impress
that way.

You're right: he doesn't know anything about magnetics, either.

I know when to gap and when not to. Something you obviously know
NOTHING about, lard ass.

How much did you pay that belly dancer to rub her sweat all over
you?

Since you obviously don't know the effect of adding a gap on primary
ampere-turns (you guessed wrong) or on flux density (you refused that
one), what is your criterion for specifying an air gap?

Cursing is no substitute for understanding magnetics.

I think the moniker "MassiveProng" must be short-hand for
crowbar-up-ass ;-)

Aside...

A bunch of us went out on the town after a business meeting at MCE,
back when they had a location in West Palm Beach.

We went to a strip joint.

One of the engineers was very young... read virgin ;-)

I offered a dancer $20 if she could make the kid sweat.

She did ;-)

Since I filtered that dork after seeing about two of his posts, it's
already "after me".

And I've been doing my best not to be a trollfeederfeeder.

Or, maybe you consider yourself a "Troll-Baiter". Are you an
apprentice baiter, a journeyman baiter, or have you reached
Master?

Prevention of saturation is the main reason, even if there is no DC

Which statement relates directly to part 2 of my question: given
constant ac excitation of a winding on a ferrous core, what happens to
flux density when a gap is introduced?


If I may ask, does "constant AC excitation" refer to voltage
or current?


Voltage. But let's let Missing Prong answer this one. since it's
related to his post.

John


based on his response, I have to wonder how much of *his* work went into
designing the products to which he refers (and which dont look that hard
either). the phrse "midgets standing on the shoulders of giants" might
be applicable.

How about filth clinging to the boots of real Engineers? I seems to be more
accurate with its constant retreats to potty language and lack of
engineering knowledge.

Then you would die in a recursive filter black hole, because you are
