[Sneap] High Voltage Isolated Power Supply

[Klaus Bahner]

Chris,
 
With a power requirement of only 1W, it seems feasible to use a high
frequency approach, which means you could for example use pot core or E-core
ferrites, separated by some solid insulator sheet. Of course this will
create a rather large gap between them, I'd guess in the order of 10mm if
you'd use a glass, PMMA or PEEK panel, which makes such a setup not terribly
efficient, but still feasible. As a downside of this approach dedicated,
non-trivial electronics needs to be constructed, the advantage is that it
certainly will be a portable solution - even without a hand truck. 
 
Hope that helps
Klaus

Subject: [Sneap] High Voltage Isolated Power Supply


A group here would like to build a ~50 kV isolated power supply to provide a
variable dc voltage to a detector.
I am therefore looking for a 50 kVDC line isolating transformer or a step
down transformer with 50 KVDC
insulation between primary and secondary sides - or perhaps someone out
there has a more elegant solution.
The power required on the HV deck is tiny - less than a watt I guess.  They
want this thing to be "portable" - at least with a hand truck.
Any ideas?
Regards,
- Chris
