The advantages and disadvantages of CBB capacitor composition

Series connection CBB capacitor assembly:

Because the working voltage of the CBB capacitor is not high enough to cover the voltage requirement range of the application condition, multiple cells need to be connected in series to meet the voltage requirements of the application conditions, but due to the inherent differences between the capacitor capacitors, The total voltage across the series components does not evenly distribute to different capacitors, which can lead to asymmetric voltage distribution.

Paralleling CBB capacitors:

The CBB capacitor assembly constructed in parallel can output or accept large currents. In the charging process, the voltage distribution between the cells is ensured by the series charging resistor. However, the inherent charging resistance of the CBB capacitor itself is a dynamic quantity and has a certain degree of dispersion, so that the control circuit for adjusting the resistance change is extremely complicated and difficult to realize. Point by point control; In the discharge process, control the discharge resistance, you can get high output power, but in order to avoid the discharge current is too large, to ensure the authorized output power, to properly control the component's energy storage.
