Ok I tested all my power supply's to see if this is a common problem. Agilent 6645A Ok EA PS 2084-10B Ok Keithley 2231A-30-3 CH1 (overshoot) Keithley 2231A-30-3 CH2 (overshoot) Keithley 2231A-30-3 CH3 Ok Keithley 2400 Ok Agilent N6700B CH1-CH4 Ok Riden DPS5005 Ok Riden RD6012 Ok Riden RK6006 Ok Spellman SL2000 (overshoot) not fair because this is a 1kV 2A 2kW psu TDK Genh60-12.5 Ok Benno |

I found an article about overshoots in power supplies, dependant on the priorities of the voltage control loop and current control loop: https://www.electronicdesign.com/technologies/power/article/21801598/getting-your-priorities-straight-managing-overshoots While I have never written a control loop for a power supply, as an embedded programmer I keep wondering why you can't combine those loops or at least observe crossing the V and I limits at the same time and act accordingly? |
