I am designing a lab power supply. I intended to have a range of 0-30v up to 2A.
So I went out and bought a 24v-0-24v transformer with rating of 2A.
I chose 24v because that gave me 33v peak DC voltage after rectification, I I kept about 3v for voltage drop out so I expected a raw 30v available, but I think something is wrong here with my choosing the secondary voltage also because I can't go up to 30v with 2A current.
Now after the rectifier bridge and regulator circuit, if I try to get a...
