Your mentor is missing the point that even for a switched mode PSU the input is 50 or 60 Hz, and *something* has to store enough energy to bridge the gaps between half cycle peaks. So you'll get mains harmonics anyway, just as with a linear PSU. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
