Is not a full wave bridge. You would have to use three of those devices to make a FWB. I cannot find a ready-made 200V 25A Schottky FWB on Digikey.
Yes I am aware they are single diodes and to make a three phase full wave bridge would require 6 not three. Three would still be a half wave system on three phase. Even at that with two in series to make a full wave bridge they are still under the 1.2 volt per diode value of the unit you referenced.
Yes, and it takes a transformer with a minimum or 14Vrms secondary to make a useful battery charger. 12Vrms wont hack it.
Have you ever built a battery charger or 12 volt higher current capable power supply with a 14 volt AC transformer and tried to charge a battery with it?
Believe me I have been rebuilding battery chargers since I was in my teens 25 + years ago and I know full well what is required to make a basic reliable battery charger and a 14 volt transformer is not it. It will cook a battery every time unless you are using ancient selenium plate rectifiers or something similar with huge forward drop values when loaded up.
For a normal safe continuous charging capable system a ~11 volt transformer with diodes that have less than a 1 volt forward drop works very well being it puts the peak voltage right in the 14 - 15 volt sweet spot for getting a common 12 volt LA battery charged up without over charging it.
The only time I would go up to 14 volts AC is for a high current fast charge/booster function that only runs for a short period of time.
I don't know where you got your theory of alternators and AC to DC conversion from but every time it gets covered here and you comment on some part of it you leave me scratching my head as to how you came to believe what you do.
I got mine from hands on practical application and basic analysis while working with design repair and redesign of 100's of such systems over the years and anm well known in my parts for my expertize on battery charging systems whether they be generator, alternator, single or three phase AC power based.
If it charges a battery I have dissected and studied it in detail and Frankensteined it into working for something else probably more than once.
