Inverter question for Jim Weir

Tim, I thought you had been around long enough to know this. Perhaps not.
There is a very special killfile called a Tarverfile. Put this idiot into it.

"Tim Ward"
shared these priceless pearls of wisdom:

-I know I'm going to hate myself for asking, but what is "three phase DC"?
-How do you determine the phase angle of DC?

You mean the alternator on my car isn't
three phase furnishing DC to charge the battery"?

FWIW...
Just because you know what somebody said,
doesn't mean you understand what they meant. g

Yes Tim, otherwise you won't be captive to Weir's massive ignorance.

Yes, it is.

Tarver

I beg to differ.

When you burn out a rectifier in your alternator (like I have on
numerous occasions) then you are only putting out Two Phase to your
battery and system.

The diodes are in the three phase alternator.

A two phase alternator would be an inherently unbalanced load.

Tarver

Yep.

So.G

Charged battery and ran load ok until I could get repaired.

That is the idea, fail safe.

Yes, it is.

It is a 3 phase AC machine - the rectifiers make DC - which is DC no
mater how you slice it and dice it, and no matter what you roll it in.

Actually, no, but I'll let you ponder on the rest of the circuit.
