Hi all,
Im doing a project on Li-ion cell balancing. The method im doing is Active cell balancing with a capacitor. Im trying to simulated it in Spice and MATLAB simpowersystems, but there is a fundamental problem with the circuits(because i tried in two environments). Some thing is changing too rapidly in the schematic. The problem is usually the cell in the middile. The switching is 50Hz and the switching signals are 180degree out of phase and not overlapping. Can anybody see large changes with time due to switching?
Ive tried the following:
Numerical snubbers over the switches.
What does help is a capacitor in parallel with the cell.Does anybody have a clue?
Ive linked to the images of the schematic.
**broken link removed**
Thanks
