If you think about what is required of a transformer, in terms of physical
size, to supply 1250VAC at 200mA, you will soon realize that such a transformer
has to big (*AND*, I only need 1/20 the power that particular transformer).
Over-designing is a characterisitic that , in general, increases size and
weight. For instance: A friend of mine designed a 5V 300amp DC switcher that
(excluding heat sinks) is about 25cm/10cm/7cm - truely a *small* package for
such a device. His design is optimal and will award him a patent. Too often
I see designs that could be reduced in size and weight if the concept of
volume and space were respected.
