How difficult is it to make a compact transformerless high voltage
current and voltage source? Is it possible to adapt the current
topology with properly rated components and achieve this affect or
modify existing low voltage techniques with such components?
For example, suppose I want a current source of around 1mA with a
1000V compliance. Could I adapt an LM317(or variant) to drive a
capable BJT for such loads?
http://en.wikipedia.org/wiki/Current_source
Shows many basic topologies for current sources and it is my belief
that ideally they all work for any voltage and current. Is this
correct? Is my problem dealing simply with component capabilities and
isolation issues?
Similarly, for switched mode topologies such as a buck-boost if I were
to use capable components(high voltage ratings) and diligently deal
with isolation issues could I expect to have success?
Potentially my issues lay with finding the properly rated components
or finding exotic methods to modify existing components for such
capabilities?
Alternatively, are there any high voltage IC voltage and current
sources?
