Advantages and disadvantages of the composition of CBB capacitors

Series CBB capacitor components:

Working voltage is not high, as a result of the CBB capacitor monomer fails to cover demand scope, the operating mode of the applied voltage in series to meet the application needs to be more monomer working voltage requirement, but because of the inherent differences between monomer capacitor in series on the components of total voltage is not evenly distributed to different capacitors, it can lead to voltage distribution asymmetry.

Shunt CBB capacitor:

The CBB capacitor assemblies constructed in parallel can output or receive large currents. In the process of charging, the charging series resistance ensure monomer, the voltage distribution between the intrinsic to the CBB capacitor charging the amount of resistance is a dynamic, have certain dispersion, to adjust the resistance change control circuit is extremely complex, difficult point control. In the process of discharge, high output power can be obtained by controlling the discharge resistance. However, in order to avoid excessive discharge current and ensure the permitted output power, the energy storage of components should be controlled appropriately.
