I can get 230V to 50V 3A transformer as the input, I dont know how you control current 0-3Ahi
can you be more specific like input range voltage and current and similarly you output requirements
Can you provide me a understandable schematic? Thanks.Its a somewhat complex schematic!
I have built one of "electronic-lab" power supply circuit about a year ago, it didnt work. Give me some info on how to make one (want to control current 0-3A) , I might be able to design a circuit. Im a first year student, I admit I don't know much, but I can try. Thanks.
This is the circuit didn't work.must work friend show me your circuit that didn't work may be we can help you .
I want to know how to control current.Check out LM338.
Not going to get much simpler than that.
You will have to add more external stuff if you want to be able to set a current limit
below 5A , but that can come later.
Sorry , didn't see the 50V rating.
Try a lm317HV with external pass transistor. Still pretty simple!!
Ok upload it when you can. Thanks.i've made 30v power supply few years back i'll give you diagram you have to wait may be tomorrow i am outside my work station ok
