Go ahead people , I need your theorizing help .
What does Stephen mean by , quote :
"Also , the frequency is adjusted to match the electrical wavelenght of the arrays" ?
Wtf ? Makes no sense to me . Must be a mistake because an electrical wavelenght in the audio ranges would be hundreds of meters long if not kilometers . Is there more to this quote than meets the eye ?
I will take all theories seriously .
So I have studied 3 phase systems before at school , we got a 3 phase power supply and everything there , I understand it perfectly when it comes from the wall plugs but this is a bit "mindbending" to me .
This is a solid state version of a 3 phase AC system , as you can see this is strange . I have made an very good 3 phase pure sine solid state driver/oscillator with some pretty powerful amplification . Phase A,B,C are 120 degs out of phase and have same common ground , they all use same power supply .
I basicly wish to connect this as a Y source , delta load configuration .

I have spent much mental energy trying to figure out how I should connect it , it is very strange to me . I have much experience @ school as I just connect the alternator leads properly for this type of connection but this seems strange to me .
It seems to me like I already have my common source point , ( ground ) , is this the right connection ? Can this even be done ? I know it can be done via a transformer Y on the primary to delta on the secondary where neutral is my ground but I wanna try with no transformer .
I can see why you might want your source to be a "Wye" configuration to keep the battery count down, but what is your reason for only thinking of the cell arrangement as a delta load?
And remember while thinking all this out, that the 120 degree phase between circuits is going to lower the voltage.
If the power circuit was run in phase,
one leg could be +24VDC,
while another leg could be -24VDC
thus making a full 48VDC swing.
But while one leg is at the peak of the sine wave (+/-24VDC),
the next is 120 degrees out in lead,
and the other 120 degrees out of phase in lag.
So factor that loss into the distribution of cell voltages.
That a basic alternator is a delta source already,
that is the only reason Stanley arranged his connections as such.
Your not limited to that way of thinking here,
you can wire your tubes as a series connected "Wye" matrix too.
In the Stephen WFC his cell is connected delta type , the boys @ allaboutcircuits said my delta transformerless would work as far as they can tell .
I am probably gonna make a 3 phase step-up transformer myself anyways with some faster core material since these dont exist , luckily the faster you go the less wire you need , this is easier to make than a VIC , wich I have made ( thumbs down , gruesome to build ) , just a big E and an I with some not to gruesome wrapping .
Will it work, yeah
Best way to go though, hmmm?
All that matters, and I see it said again and again here.
Something tried once, is worth a billion discussions...
Kinda wondered why you didn't include series inductors
to limit the current, but let the voltage build up anyway...
Well OK, if your considering a transformer interface, then go toroid,
all your anwsers lie in the work of Bob Boyce then.
Just sit thtough this whole vid (Uncut version), and rethink.
