Hi,
My success in building few small things with your active help has increased my interest on electronics and this forum.
I was planning to build a power supply with Voltage and Current regulation capabilities. This is to be used to power various equipments as well as to charge different types of batteries.
My objective was to have something within upper limit of 1.5 Amps and up to 12V in output.
I have found a circuit at
**broken link removed**
**broken link removed**
But found something in it totally unknown to me.
The line that feeds the IC2 Adjust point has originated from only one side of the Center tap transformer output even before the rectifier diode. On its passage to IC2 Adj point, it passes through Diodes, R2. R1 and a 220mf condenser.
I did not find anything like this in any other 317 based circuit. What is its purpose or advantage over other LM 317 based curcuit types?
Could anyone please enlighten me on purpose of that?
Could anyone please suggest me some other circuit to serve my purpose?
