| 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. |

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 |
