I would delete the transformer at first

Okay i did it. But now voltage is still raising... why is that?

for what exactly are trying to do with this circuit?

miki333sp

I want to build a DC lab power soruce. For experiments and other stuff. Also i would like to add gauges for voltage and amps control. An Lcd for actual parameters. So im starting with an Rectifire at first.

for a simple dc lab. remove the inductor.

put diode zener for regulated tension to output

Using diodio zener in this case because you arent using a transformer. you can use an 7812 and 7805 but look at datasheet first

Move the last capacitor to the other side of the resistor and change the resistor to 15k. You had a RC time constant on the last cap and resistor. That's why voltage rise slowly. Sometimes a very small ohm resistor is use for current limit. Then you design a circuit the will measure the voltage drop and amplify it and start to shut down the regulator

Soo. I did what you said. And its ok but wtf is this voltage?! Its 0.8v i want about 320v with 2000W power supply.

Thanks for help until now. But What to do now, guys with this voltage??

At the last comment i was mening so i want to biuld an 320v 2000W | power supply with gauges for V and amps

The 15k resistor was for the 1.5 volt lamp you used to have. But now that you replace it with the 230 volt light just get rid of the resistor.

Get rid of the Zener to

Increase the wattage of the lamp to 2000 if you want 2000 w supply.

blackfire

well in this case. you dont need the resistor because you are working with lamp with tension equal source. you dont want then an lab supply so you arent needing to limit current. in this case you dont need too the diode zener because you arent regulating tension. to get from 230 to 320 you need an tension boost. probally from an amplifier

The 230 volt source in the program are peak values not rms voltage from the wall. Boost the voltage source to 320 volts and that will give you 230 rms wall voltage. Also increase the capacitor values.

Use a transformer.

So i did something like this. Power is 2000W, right? Everything is awesome but this 10v change is output is wrong... more copacitors?

miki333sp

Is this even possible in real life? (2 inputs) i mean will it work? And can i did it the same but with one input?

blackfire

you cant put two source ac. actually you can but thats not for what you want.

blackfire

using one transformer to boost your tension. prob it will be 1:1.5 or 1:1. 7. 4 capacitor isnt needed. because capacitor is only to remove ripples. 2 capacitor with 2000uf or 4000uf is enough.

miki333sp

Ok so im pretty proud of this what we have made. But this 20v change on output isnt good enouf. I want at least only 1v change

blackfire

Extras ACs isnt necessary. work with only one AC power source and one transformer.

blackfire

10 years ago

great. now you will need to adjust the transformer for the tension wanted

Thanks for help m9 really helped

one more thing. ac power differ from country to country. therefore. you use 110v it gives 220v. 55v it gives 110v. 57v approx 115v. or 115v it gives 230v..

blackfire

each country havr your form of generating energy from frequency. on brazil it is 110 and 220v. on usa i think it is 230v. so you need to build the dc supply according with your country

Add inductors on the junction between two capacitors there in parallel. It would then be a better filter

VivekChoubey

Add about 5H inductor and do adjustments

Check web for real transformer turns. You need a zener diode in parallel with capacitor and a resistor beteeen them

Buena idea lo de la auroinduccion y la resistencia, pero no sirve, rucuerda la 2 ley de termodinamica.
