Hi everybody!
I want to make a power supply for my car audio system. For this, I need a 1.400W supply with 220Vac in and 13.8Vdc out 100A.
If anyone help me, I apreciate.
the pcb layout that was concebibo for symmetrical SMPS, being able to be 1 only:

these photos, it is the toroides what I am using in the project:

this one here, it is the schematic of the SMPS:

hi Albert,how is your project?
As i m new in the block ,im thinking about beggin my project in half bridge using igbt +2110+3525 as initial form.Voltage controled regulated power supply.Im about using n27 toroid as main trafo and searching about output inductor,mainly because i will use high bank capacitance.
Have closed the regulation loop already?

You should avoid toroid SMPS transformers for offline applications. Proper insulation is hard to achieve and usually ends up degrading transformer performance well below the level of E cores.
Or you may do like that forum member that we know who sells a product where primary mains-live magnet wires touch directly with secondary wires.
A little scratch on the enamel and someone may end up injured or dead.

No
But if you have to ask that... Think a bit about voltage, current and power on arbitrary waveforms, this is elementary electronics.
I use one of these, it's nearly the most affordable solution, unless you want to do a calibrated power calculator yourself (it was a gift from a nice customer).

It does exist, believe it or not.darkfenriz said:love that play on words

A friend actually compared it to a borrowed $800 Fluke meter and it was right on. (So for an extra $770, you mainly get a NIST certified calibration and fancy waveform displays. Not worth it for the typical experimenter. Just get the $30 meter.)
