Inverters convert DC to AC.
I understand the system, I just screwed it up when typing out the explanation. Usually generators make dc, and an inverter changes it to AC (like in a beach).. The hitch is that the TRU's are transformer-rectifiers so it goes the other way (why else would the idg's be on the AC page, feeding the AC buses at very least?). But thanks.
