The acceptable way to change your opinion is:

* add a new post indicating your new opinion
* optionally changing the early post, using strikethrough to indicate what you no longer wish other people to consider, and adding "EDIT: ..." to show your new opinion. Doing that makes you appear to be thoughtful and considerate.

"Silently" changing the early post makes you look like an insecure troll.

I did not changed my opinion. I made the original post more clear and easier to answer by adding an example of what can be inside the green box and asked two questions that can be answer with a simple Yes or No.

again  an useless thread  wholl endup shutted down ... pffffffffff


and seeing your past threads    "electrodacus"   you seem to love making some ruckus 

im not a mod, but you'd be on a warning

But I want electrodacus to provide a direct quote where someone said the DC-DC converter could provide a continuous step up in voltage without a third electrical connection. Otherwise he is just being disingenuous and misrepresenting people.

Because I really don't believe anyone on this forum would be likely to say that about the "DC-DC converter" picture in the first post.

I will try to make a search but it was over a year ago and it will be some work to search trough all those comments.
So should I understand you agree with my answers to both of those questions A) and B)  ?
coromonadalix:
i agree with nothing, you seriously need to relearn electronics / applications  and a few other things, instead of starting thread and sucking life out of many members here

all you answers can be found elsewhere

its a derailing thread  thats all       



im beginning to wonder if some people want click counts or post / thread counts   the way i see things

in the fpga or micro processor thread  one guy  started 4 thread of the same part ??? with slight differences, and before it would have been blocked,mad a complaint and its still going   :palm:

It is then connected the other way round, negative plate to V1 and positive to the output. The capacitor first discharges, adding its voltage to V1, before charging in in the opposite direction. Higher voltages are possible by connecting more capacitors in parallel and then in series for the discharge cycle.

This circuit isn't practical application. It's just a theoretical demonstration. It's possible to use solid state relays connected to a microcontroller for the timing. The microcontroller could be powered via another capacitor which is charged in series with the load resistor.

Thanks for doing the simulation and thanks for answering my questions clearly.
I think there are at least 2 or 3 people excluding me that agree with you so I'm looking for those that did not provided a straight answer but doubted that is the case some asking for simulation proof.
