Clearly, you haven't spotted the obvious flaw in your design.All the parallel lines all have more voltage than the super cap so theres no reverse flow.

I thought that this thread was mainly about constant current charging, and I was referring to the losses in the ESRThe loss to resistively charge a capacitor is independent of the time to do the charge, or the value of resistance in series with the capacitor.
The loss is always equal to the energy stored on the capacitor (1/2 CV²).
The only way to reduce that loss is to resonantly charge the capacitor through an inductor (for a perfect inductor, there would be no loss).
I prefer the term "Have a super sparkly day" which is quite likely in my opinion.Or in Disney speak: "Have a magical day"
That specific phrase is used by the actors at Disney World to convey... a range of feelings.I prefer the term "Have a super sparkly day" which is quite likely in my opinion.
Don't know where I heard it before but when I did - I thought it was some sort of blond reference.That specific phrase is used by the actors at Disney World
Because Disney World is known in some circles as the "Magic Kingdom" it seems logical that the actors want you to have a certain kind of day, regardless of their actual feelings.Don't know where I heard it before but when I did - I thought it was some sort of blond reference.
Just a clarification. It‘s a 2.7V capacitor he wan’t to charge at 30V to do it faster. How he will know when the cap is at 2.7V is not at all clear.You cannot charge a 3000F capacitor to 30V with a 30V 3A power supply faster than the 15000 seconds I calculated without violating the laws of physics. Using only passive components, you cannot charge it in less than than twice that time.
the 1pf caps are for charging the super cap, they dont have to be super caps themselves, they can just be mini ceramics.If I'm following this correctly, or at least as stated, you're talking about using 1pF caps. Supercaps are measured in the several Farad range. 1pF is 10^–12 Farad.
*Sniff* Nope.
Have you tried simulating your circuit?the 1pf caps are for charging the super cap, they dont have to be super caps themselves, they can just be mini ceramics.
Well when it doesn't work, I'll have to hide in a little hole for a while, and feel a little hurt, but I'll be back, cause a man that doesn't make mistakes, doesn't make anything.
yes thats a good idea, itll easily go into falstad. yes indeed.Have you tried simulating your circuit?
What did he accomplish that was impossible?This looks a lot like a manifestation of the "Jim Moore syndrome", thinking that if you really want something to be true, it is true.
J.M. was a person I worked with years ago, and he was able to specify things that could not exist. He was also able to improve instrumentation systems by designing in multiple ground loops into 4-20Ma circuits, which was an amazing achievement.
Heatsinks? I mean, how do you do something like that without knowing you are going to be heating things up dramatically?here secrets out..
A perfect explanation of many things you have said in the threads your in.Its just something I got myself into trying to be some kind of pointless rebel.
