Hello alok kumar singh,
I do not yet have such circuits. 12V 5A using SMPS transformer. But You may try this: I like it because it is easy.

I am sorry. If my suggestions can’t help you.
sir how to connect VR1 in variable power supply

Hello, Muhammad Aqib Ali
Excuse me.
Which the circuit do you want to build?
Hello, I own an internet tower and I want a multi-volt electronic circuit to be an alternative to the inverter and use transformers. I want an electronic circuit to convert from 12 volts to fixed multiple voltages 9v, 12v and 24v and the main voltage source is the use of a battery

Hello Hussain,
I glad that you are interested in these circuits. You should probably use a DC to DC converter as a Switching mode power supply circuit. I’m also interested in learning about this kind of circuit. In the future, I will publish it on the web.
Ah… What is the current size of the load? If the load uses less current We choose a simpler circuit. and smaller.
Thanks
i need know how can i create power supply 10 voltage with 5 amp
I’m always burning the potentiometer.help me in lm317 .I use the transformers of 220 ac/24ac . And it keep burning.my connection it right according the schematic I use just like in the example this
In reply to Arnold.
Hi,
The maximum input voltage for the LM317 is 40V. Yes, you can use 24VAC transformer. When it changes DC voltage, the voltage level must not exceed 40V. In my experience, transformers with voltages that are too high. Until the problem mentioned in the article occurred.

You may encounter the same problem as me, or in another case, you may encounter a low-quality LM317 that cannot handle voltages as high as 35V. I used to use an LM317 that couldn’t handle voltages above 30V. It would get very hot.
