Hello chaps,
I have a project here. I need to build a small voltage doubler circuit from which I will then expand to suit my needs.
The problem I'm having is that the basic one outputs 50Vdc whereas I have 240Vrms in. In this case I expect a minimum of 500Vdc. (cant post my drawing for now but I'm using this replica: http://en.wikipedia.org/wiki/File:Greinacher_circuit.svg but without the tx; using mains at 244vrms)
I am using scavenged capacitors(disc ceramic capacitors -- the small blue ones) and diodes(FR107) for a single stage half wave multiplier.
I have tried changing the diodes and using brand new 1N4007 whereas I have been through all 30 capacitors I have at my disposal. Non of them appear broken and testing a few has shown nothing contrary to my prior findings. All diodes are in superb condition.
No component is getting hot and neither are there shorts or funny smells.
Any ideas where I'm going wrong?
I need to finish it ASAP like today!
Thanks in advance.
