9V 1A schematic needed

I read in sci.electronics.design that Mac wrote (in ) about '9V 1A schematic needed', on Sat, 19 Mar 2005:

In fact, the overall efficiency, measured as Idc/Irms, is higher at low rectifier conduction angles, even though the peak diode current is higher. A large filter capacitor doesn't increase transformer heating.

the charge, (Idc / fc), is held constant. (Where 'fc' is 2 * line_frequency for a full-wave bridge, or 1 * line_frequency for a half-wave bridge.)

The DERF tranform, applied here, is described earlier in this thread.

I explained that already. See my post at 7:19 on March 19.

Looks like you're the one behind the curve. You seem to miss the point that his answer was of about the same characteristic relevance as all his other posts- he is a totally clueless nitwit, and any attempt at humor would be swamped by the overwhelming hot air, pretense, pseudo-theoretical factoid trash, and other elements of his style.

Hey, loudmouth windbag, where are all the words on the noise induced detection problem in the 40khz amplifier thread? Your days of skulking off are over- and we are calling you due, pussy, phony, illiterate trash heap boy. Looks like you ran out of elementary factoid braindead arithmetic trash and now you are be called on it- You just don't seem to be taking up the challenge, mainly because you have run out of material- not so verbose when you have to actually produce something tangible are you, punk programmer, pseudo-intellectual, and pretentious fraud that you are....like I say, you are a drowning rodent.

What's really laughable is how you similarly stupid people can understand each other so well- sort of like pedophiles and other sociopathic deviants, you all know each other instinctively. Someone with your posting history is no position to laugh at anything. You are right about one thing, you are a "F"ing"A".

This has been converted, via a process I will call the DERF transform [1]. This elision process conforms to accepted Usenet quoting practise with the exception that elided text is replaced by "[DERF]" and, where needed for grammaticality, short sequences with a '[]' pair are inserted.

Fred, you need help. Or your meds. Or both. Settle down and try to remember how it was to resemble a normal person, if you can.

No, Fred, I am not dropping it all. As anyone with the brains God gave turnips can see, you are not responding to it except with garbage removed by the DERF transform. Do you truly find it so hard to devise a rational argument, or do you see your role here as mere pontification? Do you imagine that your garbage injections here do anything but make you ever more obviously a fool?

What's important (to me, at least) is that Fred, like a couple of other parties I could name, posts only to show how smart he is and how stupid everyone else is. His posts are generally delayed, which means he went to the trouble to do research before responding, which would be admirable except for the motivation.

What Fred et al never do is try to be genuinely helpful, social, whimsical, truly interested, creative, or fun.

So don't pay him undue attention: he's not nice and he's not important.

I hope this means you fully recovered from whatever shock you suffered on account of my application of the inverse-DERF transform to what would have been empty text otherwise. I would like to know that, with a little research, you were able to discern its meaning.

Please drop me a line by email if you would like any further clarification, mitigation, or a real apology.

I based my statement on theoretical calculations, so simulations may provide somewhat different results.

Agreed. Do you find that leakage inductance has a significant effect?

A real mug's game, that is! 1 volt per farad, or thereabouts.

Yes, it does. I've done a lot of analysis of these circuits in connection with the famous IEC/EN 61000-3-2 standard on mains harmonic emissions.

(1) I doubt seriously if Fred HAS a wife, but he is, at the very minimum, mentally deranged.

(2) I resent your mis-use of the term "Old Timer"... a great many of the posters here are Old Timers... I just passed the conventional age of retirement in the US, but have no intent of ever retiring.

Fred has a mental disorder. I doubt that it is the product of just old age.

My suspicion is that he is off his Lithium ;-)

Now John, IIRC you're just a year or so older then I am. (If you're having trouble with the math I just did my 16-1/4 birthday (base 4 :)

Oh tee-hee-hee-heee. hey look at how clever Laweee Brathfeld is every body- [ yell that with lisp and childish voice....]

Where's your workup on the 40kHz amplifier thread, fairy loudmouth boy? Can't go any further with 4KTRB and some other simple-minded trash? We are not surprised, windbag. You are one little superficial and worthless moron.

Ooooh- deep, deep, question, superficial little piss ant boy and pretentious moron...Where's your workup on the 40kHz amplifier thread, fairy loudmouth boy? Can't go any further with 4KTRB and some other simple-minded trash? We are not surprised, windbag. You are one little superficial and worthless moron.

'Tweren't any this year, that's why the 1/4 ;-)

Did ya' figure that out, retard? Where's your workup on the 40kHz amplifier thread, fairy loudmouth boy? Can't go any further with 4KTRB and some other simple-minded trash? We are not surprised, windbag. You are one little superficial and worthless moron.

Your explanation is unacceptable- it is a rodent dodge, something I'm damned sure you have puuuuuuuulllenty of practice with. You're dropping it because you no way in hell can go any further- you have nothing left. Anymore who expends 500 words on a bs 4KTRB answer is a total fraud. Looks like you're crumbling, windbag- there's just nothing there.
