cockcroft-walton multiplier ann PWM

Other Hardware General Electronics

I've done some googling and couldn't find much of an answer...
my question is, is there anyway to use PWM to apply input on a voltage multiplier? instead of using AC

Sure, if a coupling capacitor is used to remove the DC component from the PWM output. Driving voltage will be about 2.5 Vrms.

You need a series resistor to keep the PWM output current from exceeding about 20 mA.

this thread was started to try to understand the theory. I don't plan on building anything...…. yet

Dave Jones explains the theory here.

I watched this, I watch the EEVBLOG regularly. But in his example it looks like his power in to the multiplier is taken off a transformer, so he is using AC voltage?
unless I missed something in the video...
My curiosity is to weather or not one could use PWM vdc on the input of the multiplier.

Yes, as stated in reply #1.

Yes. The tone() function would also work as a way of driving this kind of circuit. That would be my choice.
