High voltage regulation with RedPitaya

Post by kolvik_chalmers » Tue Oct 11, 2022 1:58 pm

Dear all,

I am new here and I'm looking for a way to regulate some lab equipment using the RedPitaya as a PID servo. I have found ample information on how the device can be for the purpose, but I have a slight problem with the output voltage. Since the device I'm regulating is a piezo-electrical element, I require strong voltages to make a noticeable effect in the regulated system. I think that the RedPitaya I want is the STEMlab 125-14 but the output I need is 0 to 60 V, not -1 to 1 V.

Does anyone have any suggestions on what kind of amplification circuit could be suitable for this application?

Dear Johan,

If you want to design it yourself, you can use any amplifier that is capable of dealing with 125 MHz and fits you specifications.

Otherwise, you can ask the company Mini-Circuits. They are specialized on this field and can probably help you on this topic.

Good luck with your project!
