Just a voltage regulator. To step up low voltage of minimum 60V to 220V and step down or dissallow voltage of above 240V.So is it a voltage regulator or an inverter?
I have very little experience on building any actually. But can u please explain the diference btw the transformer with tap changer and the ordinary transformer for me please. Because i initially intended to construct the transformer using normal corper winding coil technique wound around a core to d specifics actually( as it is in recoiling eletric power motor).Ok, so you want 22A at 230V output. For that if the input is 60V you need 83A, with efficiency accounted roughly 100A.
What kind of experience do you have? I personally wouldn´t try doing such a thing without having great experience with at least a 500W power supply beforehand.
Unless of course you want a big transformer with a tap changer, that might be a lot easier.
