The article on switching HV power supplies was in the Feb. 91 issue of QEX.
It should be available on the QEX CD. The article included a complete
schematic, parts list, one photo and several block diagrams. It was written
by Timothy Hullick, W9QQ. There were some corrections in the August 1991
issue of QEX.
The power supply listed the following description:
V out = 2000 volts
I out max. = 1.5 amp.
I inrush = less than one amp.
V regulation = less than 100 volts change from no load to full load.
V ripple = less than 2 volts.
Duty cycle = 100 %
Switching frequency = 100 KHz.
Weight = less than 8 pounds.
The AC input was 240 volts ac.
Hope this helps.
