Why don't you ask the person you got it from? He is not to my reach now. But, since i need to assemble the components in its PCB now, i though i should know how the circuit really works, for which i posted the doubts i got from it. one was built earlier and was running. Neil Kurzman said:
So it is a constant current source with less than 30mv ripple. yes. Neil Kurzman said:
Then it regulates current and voltage. It would only work with a constant load. Or you you are not sure? the load is constant. the current is being set according to the load using potentiometer R17 connected to LM358 i/p. recalling the details, suresh said:
Details: The circuit is designed for plating purpose, for which the ripple voltage must be less then 30mV. So that plating is not grainy. The plating time can be varied using a timer that cuts the i/p of regulator when set time elapses. kai said:
This circuit will never work! iam interested in knowing the reasons. |
