Compared with ordinary capacitor, the structure of super capacitor is improved and adjusted, and the principle is optimized. However, the function of supercapacitor is similar to that of conventional capacitor. The functions of the new capacitor device are mainly manifested in the following aspects: bypass, decoupling, energy storage and so on, which have an obvious regulatory effect on the circuit operation or storage charge. The specific functions are as follows:
(1) Bypass. The bypass capacitor in the super capacitor can store electric energy regularly, but when other components need energy in operation, they can release the charge in time to maintain use. The maximum function of the bypass capacitor is to balance the charge output of the voltage regulator, avoiding circuit failure caused by charge transmission confusion. The device has strong flexibility in charging and discharging, as shown in Fig. 2

(2) Decoupling. Decoupling is mainly aimed at the "coupling" phenomenon in the circuit. Coupling is a kind of "noise" caused by the imbalance of current and resistance in the circuit, which is not conducive to the balanced layout of the internal load of the circuit.
After using the supercapacitor, the coupling phenomenon can be effectively eliminated, and the parameters in the circuit can be maintained in the standard state.
(3) Energy storage. Whether it is a common capacitor or super capacitor, the storage of charge or electric energy is a very critical performance. Supercapacitors have larger charge storage capacity and can meet the needs of more electronic components.
After the super capacitor transmits the stored energy to the output of the power supply by using the converter lead, the storage performance of the capacitor can be further enhanced after optimization.
