Ensuring Stability in Supercapacitor Series Stacks

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.
