@Job, I forgot to add that most modern UPS have a thermo-fuse built into the transformer which break circuit if when the transformer reaches a certain temperature. In your innovation, when you build the transformer, pls do literally bury in the core a thermo-fuse but you will need to find the manufacturers heat rating for the tranformer. I did these things many years ago, so its all trickling back, one by one.... sorry for the piece meal thots. :-)
