Isolated, regulated, toroidal step down transformer AC power supply design.

[Mark]

Can anybody point me to a good design of same.

240 VAC in, 9 VAC out.

The closest thing in terms of a transformer that will be able to
provide 'some' regulation is a ferroresonant one. They were often
used 20 or more years ago but declined more quickly when the UPS
became cheaper.

The yare good at supply regulation but bad for noise and bad for
waveform distortion.

You dont really want to design a ferroresonant in a toroid unless
you want to spend a few weeks getting to grips with the material
properties and all the magnetics calculations and building many
prototypes.

Far better you just get a good SMPS.

But do you really need 9vac for your application or is that to feed
something else that could utilse DC more efficiently ?

or did phil write this so i can practice typing and get even more proficient

**Why don't you tell us what you are trying to actually do, rather than
telling us what you think you need?

As you may have guessed, your request is difficult to satisfy.

At a minimum, you need to tell us:

* AC or DC
* Maximum and minimum current requirements.

He wants a transformer that regulates.

I am trying to build a 240 VAC in (or even 110 VAC in, I really don't care)
9 VAC out, regulated (to 9 VAC) , isolated (from transformer), step down
transformer and AC power supply.

Input fused (at about 2 amps) but I could adapt just about any design to
about that current.

There...but I think I already said it, didn't I ..Let's see?



.... yes, thats me.

.......ah, I did.

What is the application?

Do you need a regulated 9V RMS Sinewave output? What for?????

[Mark]

Yes, I really do need 9 VAC for my application.

Within the application, the 9 VAC is rectified, filtered, regulated (to +15
VDC and -15 VDC) and then filtered again.

So the input needs to be regulated to within about (+ or -) 1% 9 VAC.

 

[Mark]

Yes.

No, I think I want to regulate the output of the transformer.

The output of any transformer is only proportional to the voltage of it's
input. AFAIK, anyway.

So if the volts in aren't nominal, nor is the voltage out.

*** Thanks...thats the best laugh I've had for ages
I'm sure a single 9Vac supply will give you amazingly clean +/-15V rails,
you'd best make sure you get a 500W toroidal though, that'll help..
