Designing PCBs for HV applications upto 6kV
« on: December 07, 2024, 02:21:35 am »
I've been trying to build HV pulser for one of my experiments. After a lot trials I finally got one of Behlke's a MOSFET based switch (HTS-61-03-C). I am trying to design a PCB to mount this switch, an AC-DC converter to get +5V to power the switch and connections to mount the SHV mounts for HV input/output.

I know Altium and Eagle have in-built features for the same, however I have no direct access to these software. So, I am trying to design it using easyEDA or KiCAD but have no prior experience in designing boards for HV applications.

Can anyone comment on implementing the creepage and clearance rules needed for HV PCBs using easyEDA or KiCAD.


Also, here's the drawing for the switch : https://www.behlke.com/pdf/drawings/compact_series_79x38x17_single_drawing.pdf

For Kicad have a look at this link: https://forum.kicad.info/t/introducing-kiclearance-to-auto-generate-clearance-rules-from-a-simple-table/51706/1

It's a clearance rule generator.  You make a table with all your net classes and just define the distances between them. then run the script and it will generate all the rules that Kicad needs. It's only clearances though. It won't recognise that a slot may fix creepage issues.
