Hi everyone,
I'm working on voltage equalizer for supercapacitor stack.
Attached is the schematic for my project.
Now I have a problem with driving BJT, that will allow the supercap to dissipate excess power through the resistor R2. In order to do this, I try to use an optocoupler, PC817, which received logic level input from microprocessor.
I also try to set up the darlington pair as shown in the circuit, so there is no need for external power supply. But basically use power from supercap to drive the BJT.
My question is, will this circuit be operational? (I've not buy these components yet, as I'm not sure it will works)
What are the things that I've miss, if there is any?
All suggestion is welcomed.
Cheers!
