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?
