For a specific project , I need to create a Voltage-Current controller circuit that will be able to control the flow of Current and the voltage by using 2 different potentiometers for each.
Here is the schematic I have tried....
TIP122 Darlington for increasing and controlling current, till that it is working fine but
the IRFZ44N MOSFET part doesn't work properly for voltage regulating and I am unable to find a way to fix it.
But this doesn't seem to work.
can anyone please point me out where i have made a mistake? Explanation with circuit schematic will be much preferred and appreciated.
i need one potentiometer to control voltage and another one for controlling current
I don't want to use any types of IC for this project so please avoid suggesting one till there is another way/ways left.
Thanks for your precious time.
