I'm working on a project. It's basic one: POWER SUPPLY
It can provide output voltage: 24VDC, output current: 4A.
I use LM317 regulator, in association with op-amp LM301. This circuit diagram is included in LM117 datasheet, with a pass transistor (I use 2N2955)
(I downloaded it from somewhere by searching in www.google.com)
But now, I have some problems:
- When the load is decreased immediately. It would cause increase in supply current. The output current can gets over 4A (unwanted case). So I want to protect my power supply from overcurrent. I think that I can use a current limiter. But I don't know how to use it and now, I do not have a current limiter circuit diagram. Can someone help me? can you recommend me a current limiter circuit diagram!
- The second problem is: Can a current limiter protect power supply from short-circuit (R out is approximately zero ?)
Thank in advance!
