What are the main functions of supercapacitors

The main functions of supercapacitors are:

Compared with ordinary capacitors, supercapacitors have been improved and adjusted in structure, and have been optimized in principle. But during use, the functions of supercapacitors are similar to those of conventional capacitors. The functions of new capacitor devices are mainly manifested in bypass, decoupling, energy storage, etc., which have a significant regulatory effect on circuit operation or charge storage. The specific functions are as follows:

(1) Bypass. The bypass capacitor in a supercapacitor can regularly store electrical energy, but when other components require energy during operation, they can release charges in a timely manner to maintain use. The main function of bypass capacitors is to balance the charge output of the voltage regulator, avoiding circuit failures caused by chaotic charge transfer. The device has strong flexibility in charging and discharging.

(2) Decoupling. Decoupling mainly refers to the phenomenon of "coupling" generated within a circuit. Coupling is a type of "noise" caused by the imbalance of current and resistance in the circuit, which is not conducive to the balanced arrangement of internal loads in the circuit.

After use, supercapacitors can effectively eliminate coupling phenomena and maintain various indicator parameters in the circuit in a standard state.

(3) Energy storage. Whether it is a regular capacitor or a supercapacitor, storing charge or electrical energy is a crucial performance. Supercapacitors have a larger charge storage capacity, which can meet the needs of more electronic components

Supercapacitors transfer the stored energy through converter leads to the output of the power supply, and after optimization, can further enhance the storage performance of the capacitor.
