I know that a voltage doubler (the old Capacitor/diode circuit) does a good job of multiplying. My question is probably simple......
If you feed the input of the Voltage Doubler with pure DC....
(instead of AC.....)
I am fairly certain you would have a 'zero' output.
The Capacitor would simply block the DC.
The reason I am making this question....is that I have a 20 VAC power supply that can be 'switched' to provide only 15VDC. i.e....it can supply either AC or DC. (but not both.....)
So...I would like to build something that would be able to tell the difference of what the supply is switched to.............
The first circuit that came to mind was.....The ol' Voltage Doubler.
What do you Electronic Gurus think? good way to detect the difference???
or.......??
