John,
I agree with your comment in today's environment but the
implementation of the required 'green' technology will require almost every
household and commercial electrical product to run from a SMPS. (Well maybe
a dumb toaster won't require it, but it could be designed to run on 230V and
then take twice as long to make the breakfast toast in those countries using
115V.)
Everyone wants smart technology everything so this new scenario
should come about rather quickly (maybe in a generation or less). The
customer won't care what the system voltage is; perhaps the power company
could find clever ways to take advantage of this and relax their system
voltage regulation requirement. Or maybe it won't be the power company
controlling this but, rather, the smart grid taking power from all the
neighbors renewable energy stations and sharing it locally. Should be an
interesting time; by then we will have learned more about both protection
and operation under these broader V conditions - brownout saver circuits for
the low end and better OV protection on the other. It looks like fun times
are coming to a power system close to you.
