[Convert 0-30V 3A PSU to 5A or more]

I like to have the schematic and components list used by Mr.Kain to finish my project sucessfully.

I am able to get only 1.5 Amps @23V not at 30 Volts.

Please do the need full as I am kept working on this for a long time.

[0-30 Vdc Stabilized Power Supply]

We have tried the 0-30 V circuit and have a differnt problem.

1.At 26 Volts we are able to get 2 Amps constant output...but in between 26 -30 Volts we are able to get a current of 600mA - 100mA max.What is the reason any sugession please.

2. we ahve used a transformer sec., rated at 3 A max.

3. What modifications should we need to do to get a constant current of 3 A at 30 Volts.?

Please suggest its very urgent.

I built the power supply for 3 A and faced the following problems.

1.When pin 6 of U2 is connected to the circuit the IC heats up immediatly.

connection and componects changed no.,of time but the same problem repeates every time.

2.The control is 0 or 50 Volts ,why so?
