Topics Covered
Managing Voltage Imbalance in Supercaps
The Importance of Grouping Supercaps by Capacitance and Leakage Current
Balancing Cell Voltages in Supercaps
Implementing Supercap Balancing Schemes
Technical Brief Overview
When supercapacitors are placed in series for higher voltages, imbalances can occur due to differences in capacitance and leakage current. Designers use balancing circuits and group supercapacitors with similar values to ensure voltage balance and prevent degradation, enhancing reliability and durability.
