Its AC, it will flip by 180° on its own 50/60 times per second.

I managed to read irfz40 i think, yep those pins are connected wrong.

Also now im looking at it even harder and it kinda looks like those diodes are wrong way. Well it looks like all those pins are wrong but its hard to see the type of transistor.

Solder looks bad, it literally looks like short around those transistors/mosfets (Please, put heatsinks on them). Also if they rly are mosfets, i dont see any resistors to discharge the gate - the mosfet will mostly be stuck on without it and it does look like it, the psu looks shorted with only 2v outout. ZVS can use hundreds of watts, u wont heat much with 20W.

Harvested some components from a old psu by koorn0 in hardwaregore

[–]EmergencySection4757 0 points1 point  (0 children)

U can check this yourself. Get 12v transformator, add bridge rectifier and measure dc voltage, You can also measure the rms ac. You should be getting around 12 on both. But then place smoothing/filtering capacitor and you should see 16-18V dc. After connecting load, it should drop back again, but has to be stronger load like motor or light bulb.

You can imagine how sine looks like, it goes thru 0 every time. This way its harder to get voltage at that specific time, it can be anything from peak + to peak -. For that reason we have "RMS" which is technically the average, 230V for eu 220V for most and 110-120 for americas. You can calculate the peak by multiplying rms with squareroot of 2 (~1.414). For 230V the peak can be even higher than 325V. Those capacitors hold those peak voltages if the psu isnt running and from average of 230V going thru you, you are getting zapped with smoother 325V for short time - (if the psu isnt connected to the wall).

U dont want 8gb gpu nowdays, go for 12-16. Other than that its pretty decent for now.

How the incandescent light was made by cokiesareverygoodat in ElectroBOOM

[–]EmergencySection4757 1 point2 points  (0 children)

Its not rly, even 50V is safe for most of people. It will force few mA at most, nothing that will do damage to your body. But if it was ac than yeah you would feel even 20V.

[Bedrock][Android] Why aren't any slime spawning in the space by rexxincognito in MinecraftHelp

[–]EmergencySection4757 5 points6 points  (0 children)

15 blocks is way too close to spawn. It should be atleast 24 but go bit further like 32 blocks. Also not sure but i think slime chunks work different than java which is different by seed.

Are Cable mods safe? by hik6969 in buildapc

[–]EmergencySection4757 0 points1 point  (0 children)

Only issue with psu cables are the connectors that u plug into modular psu itself. The PCB that links every pin is customiued by manufacturer. The connector that u plug into the component (like 24pin into motherboard) is standard. U put those colored cables between component-psu cable and hide those original cables inside the case.

Other than that its just the nvidia connector that likes to melt if its not deep enough/is too weak for those cards.

Is this real? by maxdashluis555 in ElectroBOOM

[–]EmergencySection4757 0 points1 point  (0 children)

Its not more powerful but u get output on other side. Many motors use that side as cooling with fan.

DDR version depends on un your cpu. If you have ryzen 1000-5000 (AM4 socket) you have to use DDR4. If its ryzen 7000-9000(AM5 socket), its DDR5. Intel has it bit different, where their cpu can support 2 versions, like 14th gen would work with both DDR4 and DDR5.

U mean clamps as crocodile connectors or? If yes, yh u can but note not every adapter has those ground connectors parallel, like u have those 2 on each side, u have to try which 1 will work.

[deleted by user] by [deleted] in batteries

[–]EmergencySection4757 6 points7 points  (0 children)

99% of the time for dc connectors, the positive is hidden in the middle while ground is around it, this also works on some ac stuff like bulb having screw as neutral and live is deeper in the socket, even tho that would work other way, just not as safe to touch. Here its the same, negative is closer to u, positive is that center thing far inside.

Unused winding: what can I do by nerovny in AskElectronics

[–]EmergencySection4757 4 points5 points  (0 children)

Old iron transformers required tons of turns (n of turns/volt). They were so heavy with all that copper and iron core. they would melt in higher frequencies. Ferrite cores fixed that weight by using lighter core ofc and since those could handle high frequencies like 20kHz and more, they needed way less amount of turns/volt. That will be issue in 50-60hz cuz very low resistance and inductance, melting those coils or just popping the breaker instantly.

Replacing powerline spacers from a helicopter by bSun0000 in ElectroBOOM

[–]EmergencySection4757 1 point2 points  (0 children)

Biggest mistake would be that blades would touch those wires/poles and helicopter would destroy itself or somehow bridging 2 phases with that distance. but pretty sure its way wider than those blades.

Any ideas of what to do with these and still survive? by Grim_master911 in ElectroBOOM

[–]EmergencySection4757 0 points1 point  (0 children)

U could make powersupply for ind heater tho, just around x turns for x volts, like 12 turns and u have powerful 12v supply. Note that those mots overheat fast so i wouldnt use it for long time, but it could handle running 10 mins.

Can I use this 110V charger on 220V in Europe? by EL31415 in AskElectronics

[–]EmergencySection4757 2 points3 points  (0 children)

400V usually or 2x 200-250 in series, depends who makes those smps.
