2 channel isolated testbench power supply

(1/1)

bogdant:
I am trying to design a 2 channel liniar power supply: 0-30V, 0-2A. I have a STM32 used to measure current and voltage. My question to you is: If I have separate gnd_ch1 and gnd_ch2, what topology is used to measure current and voltage but the supply to remain isolated.

rvalente:
For each measurement go with a uc. Suplly them with a flyback power supply with multiple secondaries (or use a off ghe shelf brick). Feedback de values with an photocoupler.

Check the isolated channel scopes service manual for inspiration.

JuanGg uses two controllers in master/slave.  https://juangg-projects.blogspot.com/2019/05/linear-lab-power-supply.html
