we can stepdown the voltage from 230/12v ,and we use the
voltage for various electronics components why can't we
step up the voltage from 12/230v if we can shall we use the
voltage for domestic single phase supply

Answer Posted / ashish

if you are going for a step up voltage then the voltage
source at lower level (in this case 12v ) has to be very
strong i.e the 12v side should be able to feed the high
current rating of the equipment connected to 230v such as
AC, fridge, water heater , mixer, microwave etc and imagine
if few of the equipments are running at the same time then
amount of power required which the 12v source has to
provide ...its difficult...
and also in such case the insulation level, the conductor
size etc has to be worked out for ECONOMIC point of view ...
its difficult..
