Can voltage across diode change if there is an open switch in the same branch?
My circuit is:
The transient analysis produced this plot:
Look the at plot of \$V(5)\$, the voltage across the Zener diode (yellow color). Why the curve is not zero before \$140ms\$? I expected that ...

Real current of bridge rectifier
I am working on a low noise 5A 0-24V linear power supply. I cannot decide which rectifier I should use.
Bridge Rectifier KBU10M is rated for 10A, but I doubt it would be able to handle this current. ...

Why do my power supplies keep failing? [closed]
I'm building a circuit to control a stepper through the generation of two sine waves, 90 degrees apart.
It's reasonably simple and has been previously tested, almost without changes, on a breadboard. ...

Zener inside a diode bridge
This comes from an LT application note, but I found the topology in other circuits too.
The rest of the schematic isn't really relevant, this is the section I'm interested in:
It seems to me some ...
