It does not work or you don't know how make the circuit?it does not work..The problem is that I don't know the leakage current of the supercapacitors..
The problem is that you apparently didn't understand the circuit's operation principle. It's expected to balance the capacitor voltages before you start to charge it.One example that it doesnt work .Let's say one capacitor has an initial voltage of 0.6 and the other one of 1.8.
If I start charging them they will charge at the same rate but but the second one will continue charging beyond 2.5.
The balance generator has an impedance of 470 ohm and thus will have a 500 sec time constant and possibly a permanent offset with higher leakage currents. But the circuit behaviour may be on purpose.milvapp, there is an error on the circuit diagram.
Without additional compensation means, the suggested modification will most likely create an unstable feedback loop and force the circuit into permanent oscillations. This won't hurt the capacitors but cause an unwanted current consumption.What is should do, is to compare the battery junction to the 1/2 V set up by the two resistors the difference being amplified which then feeds more or less current via the 470 ohms into the battery junction.
The circuit misses a DC path to inverting OP input.
