I've been thinking about building/getting a HV bench power supply for prototyping, testing, experimenting, etc. I know Heathkit offered a few options.
Ideally, It should be variable within a range of, let's say, +200V-600V. Or even better yet, provide the option for a bipolar supply in the range of +/-100V to +/-300V.
There is some interesting reading here:
Bench Power Supplies
One thing I've been thinking about is using nickb's PIC/three quadrant triac, he discusses here:
MOSFET Dissipation (for Power Scaling / VVR) #53
Assuming that the PT has a robust VA rating, is there any reason not to use something like this for a variable bench supply?
Also, is it worth regulating the supply for something like this?
