Hello Ron,
In my workshop I use an old Schenck engine test stand with eddy current brake (WS260).
The controller is a Yourdyno with a self-made power supply (voltage regulated 0-192 V with PWM control)
This has worked very well for several years.
Do you think your DB3 Power supply is a simple powerful upgrade for my configuration to improve responsiveness?
I'm a bit scared of EMC.
What version of the DB3 should I buy?
Many greetings
Frank
Hello Frank,
If your current power supply doesn't have any fast demagnetization circuit, then there will be significant difference when you upgrade to BD3. The difference should be comparable to the difference between my BD1 and BD3. You can see it on a video here:

You may also have another improvement by using my DC1 series controller. It has 500Hz PID loop. Some time ago I checked and Yourdyno had the update rate limited to 20Hz. I can't seem to find this information now.
EMC is a thing to take seriously. You should use input AC filter and shielding to avoid problems.
BD3-22.5-250uF will be suitable for your eddy brake.
Best regards
Ron
Found it. 20Hz is still there as "Brake control update frequency" maximum value in version 3.3.35 from May 2023.
