The main function of supercapacitors

Supercapacitors have been structurally modified and optimized in principle compared to conventional capacitors. However, supercapacitors function similarly to conventional capacitors during use. The functions of the new capacitor device are concentrated in the aspects of bypass, decoupling, energy storage, etc., which have obvious control effects on circuit operation or storage charge. The specific functions are as follows:


(1) Bypass. Bypass capacitors in supercapacitors can store electrical energy on a regular basis, but when other components require energy during operation, they can release the charge in time to maintain use. The maximum function of the bypass capacitor is represented by the equalization of the charge output of the regulator, avoiding the circuit failure caused by the chaotic charge transmission, and the flexibility of charging and discharging the device is strong.


(2) Decoupling. Decoupling is mainly for the "coupling" phenomenon generated in the circuit. Coupling is a kind of "noise" caused by the loss of current and resistance in the circuit, which is not conducive to the balanced arrangement of the internal load of the circuit.

After the supercapacitor is used, the coupling phenomenon can be effectively eliminated, and the parameters of the parameters in the circuit are maintained in a standard state.


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

After the supercapacitor transfers the stored energy to the output of the power supply using the converter leads, the optimized processing can further enhance the storage performance of the capacitor.
