Hey, listen to the guys - am just a student on the A320 too-
however, AC>TR>DC
>
Given you have 2 main engine gennys AC whose power is turned to DC through the TR (Transformer Rectifier) ok?

Now, the power - when your AC gennys . . fail can be obtained from the batteries, although this is decidely limited, but you know that right as you are studying the Electrical system as we speak . . . ? This batt power is DC, so it has to be converted to AC to work AC services.
>
So, the batt(ery) power is DC------DC>Static Invertor>AC
so the power which is DC when fed through the static inverter, becomes AC.

>
AC>DC>TR (note they are all letters)
DC>AC>Static Inverter, ok? Look on the Electrical diagram and you should see this in seconds, its on the electrical ECAM SD.

edited later: - or, in short, as ECAM surprise said.

But then again, maybe it wasn't a question on the Bristol G/S database

- that was funny . . .
