What does the efficiency bell curve of a good power supply look like? Should the curve peak out at typical load?
Is it realistic to expect a 85% efficiency from 10W to 1000W load from a switching ps?
the input voltage will be 3phase 115rms phase to phase. There will be 4 48V outputs. The combined power of the outputs will be 1000W and there is no cost limitation. I guess the output loading is stable and does not swing.
