Increasing transformer efficiency
All electronics are really DC powered, even though they are fed AC from the grid, which means that each TV, DVD, SAT, stereo, computer, etc., has a transformer+rectifier inside. How efficient is that? Would it be more efficient to have one larger transformer supplying power to the LCD/DVD/SAT/home theater bundle in the living room (hacking those devices to directly input DC)?
From Wikipedia - Tranformer, Energy losses: Quote:
So the question remains: Several small transformers, or one larger one? |
