I need to build a simple 0-30v 1A power supply for my lab projects.
I am trying to achieve a regulation by using a darlington pair, an error amplifier transistor, negative feed and zener diode as a reference voltage.
I have built the circuit on a breadboard but when I connect a load the output voltage drops significantly!
I realized that 2N3904 transistor can not handle the current passing through it and gets burned so I replaced it with BC337 but still no satisfactory output regulation.
What am I missing here ?
Thanks for helping me out.
