I have a bunch of high voltage capacitors and diodes to make a CW voltage multiplier. I am encountering problems with ZVS circuits and and flyback transformers. The ZVS drivers keep blowing up. I was wondering if I could use an old 60hz NST to drive this multiplier circuit. I’m not sure how much frequency affects the performance of it.
I also have the newer high frequency NSTs but I would have to play with their protection circuits because those can be problematic. They are worth a shot too though.
It seems like one of the easiest ways to reduce the weight and lower the material costs of some sort circuit that requires a high DC voltage would be to replace the transformer and rectifier circuit with a series of voltage doublers, but every old radio receiver, high-fi, amplifier etc I’ve ever been inside uses a power transformer. The only place where I’ve seen voltage doubler circuits is in televisions, to supply 2kV or more to the cathode ray tube but even in those the other power tubes are supplied their B+ from a transformer. The men who designed those circuits certainly knew better than me, but I would like to know why.
Hey guys, just bought the new Razer 15 (RZ09-0410) with the 11th Gen i7-11800. I was hoping to play around with OCing and saw a lot of competitor laptops were able to push the same specs pretty far - but their brand (MSI) doesn’t lock the bios for the machines so they were able to use XTU.
My cinebench score is at 9800 but these other guys on YouTube are pushing 15000. Close to Desktop performance, so I’d love to try it.
Unfortunately Razer is known for being more safe and numbing down the potential for their laptops. I’m not versed in flashing bios’ and doing any kind of hardware changes to get these unlocked so I was wondering if you or anyone you knew offered a service to do this.
I built a high voltage wand similar to the one electroboom and join the technicians made. Currently, I have the secondary of the flyback connect to the circuit’s gnd. Is this dangerous because the voltage multiplier’s low frequency? Should I keep the secondary grounded? If I have the secondary floating, would I be able to touch the sparks?
Hey, so I'm trying to make a small go cart. I've got 4 Segway motors that have a nominal voltage of 54.3 volts and I've got a spare car battery lying around. I'm hoping to be able to use it for its sheer size and capacity(plus its free).
So is a voltage multiplier circuit going to be provide a stable enough output for something like this?
or should I just build a LiPo battery bank?
Should I be concerned with anything overheating? if so what would Overheat?
I have this Circuit I want to use it to drive my 20x voltage multiplier and take out the one 3x multiplier present. these two pins are the ones outputting approx 1000v right?
I can't find the pinout for this specific transformer at all, and the schematics I linked don't have a transformer
I'm wondering if you were making a villards cascade, could some of the capacitors be around 150nf and some 100nf?
I don't think that it would work, but if it would, that would save me a few days of shipping time because I already have the capacitors on hand.
Hello!
I'm a chemistry student trying learn more about electronics.
I decided to build battery powered Geiger counter using SBM-19 tube. One problem I have is getting the 400v that the tube needs to be operational from 5v that I will use to power microcontroler. Previously I used DC- step up converter but it wasn't to reliable.
What other solutions for that can you recommend?
Is Cockcroft-Walton generator sensible idea for battery powered system?
I'm using the MSI B450M DS3H with the Ryzen 5 1600 and have been trying to overclock it for a while now. I know what I need to do but everything I need is greyed out. I've tried circumvent it with ryzen master and easy overclock but those never save after a restart. Any help is appreciated and I'll provide what I can if you need.
Can i power a Voltage Multiplier with a dc voltage or does it have to be ac
And if it has to be ac how do i get that since i only have a dc PSU
Hi Reddit,
I'm trying to reproduce the ac/dc voltage multiplier show in picture below.
For comprehension, it is the stage that creates the 400V DC for a Geiger-Muller tube.
But I didn't find this configuration anywhere, and can't figure out if there is an error on the schematics...
I made the exact same circuit and I have 200V between ground and label point "up stop"...
Can someone help me getting this right?
So much thanks in advance!
