При подключении низковольтной нагрузки будет бросок напряжения около 300 вольт, поэтому сначала подключить нагрузку, а потом к сети 220. Иначе будет катастрофа.😊

[@phuochungcnc1999]

trước có dùng cho 70 bóng led 3.3v nối tiếp, thấy rất ok, mình còn cho nó nháy nữa bền lắm

[@vanchi9044]

Không tin =))

[@AndyFletcherX31]

It is worth noting that this circuit does not provide any isolation from the 230V AC supply which means if you touch any part of the circuit when energised you could receive an extremely painful and dangerous shock from it. Remember that Neutral and Line connections are not guaranteed to be any particular way around. Only use capacitor dropper circuits if you are absolutely sure there is no possibility of anyone coming into contact with any part of the circuit.

[@saddle1940]

And you should never drop high voltage across a single carbon 1/4 watt resistor. Use at least one in series per hundres volts.

[@alexanderrice5224]

@@saddle1940 Yeah, I came here to say basically the same thing. Firstly, this circuit is not something that electronics beginners should be encouraged to build. If you're learning electronics off KZbin videos there's a good chance you're not aware of how to safely handle mains voltages... and what's worse, the way it's built in the video shows a complete disregard for even the most basic safety precautions. Secondly, the version of this circuit shown is a downright dangerous design: there is no fuse, no isolation, no earthing, no enclosure and if that 1/4W carbon film resistor fails it will pass mains voltage to the output.

[@luiseriverar9939]

There is a difference between the diagram (C26-100uF) and the assembly (10uF-400V)

[@Fire-Bug]

Perfect and clean design for various purposes.i Tested it myself and found it legit ❤

[@wasimshaikh6896]

how much current you can draw from it? pls test & reply

[@Fire-Bug]

@@wasimshaikh6896 you cant run 12watt led bulb on it due to flickering but if you increase its voltage capacity then it might run. An example for u is that replace its capacitor with another value such as 4.2uf or so with 400V then it might work on 12 watt led bulb. Rest u can do the math. Or look for another circuit that u test ur self. I found many fake circuits on youtube. For small load like 10mm led it will work perfect.

Does this supply apply voltage automatic to inject voltage into the components?

[@abdulbajeed189]

Can we get two different output voltages at a time ?

[@Palmit_]

not from this project alone. the only possible way is to have the required end current be less than the forward current of the last led in the chain. and the same for the led before that, and the led before that.. etc etc..and so, basically, you need a resistor for each led, which kind of reduces the effectiveness of the project.

[@luisglaucio5111]

Caríssimo, eu sou de Pernambuco Brasil, passe a relação dos componentes principalmente o capacitor grande.

[@boblewis5558]

Yes it works BUT, and it is a B I G BUT, potentially lethal! Users should use GREAT caution with such circuits to ENSURE that the output is never exposed to external connections. ALWAYS fully enclose all the components inside an insulated case and use great care when modifying, servicing or otherwise having direct access. Use with external LED strings is HIGHLY inadvisable ... Use a fully isolated supply instead ... A switched mode constant current supply found inside mains LED bulbs is a FAR safer option. 🤔🙄

Sir I have 35.0.35 transformer, I want to convert it to 24.0.24. Is there any option to convert it? Actually I need 30 to 40dc volts for the amplifier in dual supply.

[@boblewis5558]

You should DEFINITELY learn more about creating DC supplies from mains before continuing for your own safety. However: Bridge rectify your AC use an appropriate voltage rated bulk storage capacitor AT least 1.5 times the maximum RMS AC voltage. Then use a suitably rated switch mode buck regulator to achieve your required final output voltage. Please consider carefully your required output current and power and ensure your bulk supply is capable of delivering that.

[@mrsingh-wt8ep]

@@boblewis5558 Thank you sir but how to get negative voltage?

[@bhadawang]

Thank You

[@mokshved]

Learning purpose is ok if you use it on a regular basis, then not useful. After some time, the capacitor and resistor both lose value of current, then the first resistor defuse, then the capacitor blasts. Many times I try this type of circuit for LED series lights, and every time the same issue comes out. Not useful for long 1 or 2 hours

When using capacitive voltage droppers of ANY kind ALWAYS use X series capacitors of MINIMUM 275 volts rating, preferably more. It is not sufficient to JUST use 400v caps. X series have very specific designed-in safety features that normal 400v caps DO NOT HAVE!
