For dynamic voltage drop devices
Although many users choose uninterruptible power supply (UPS) as a remedial device for power supply when the grid is powered off or the grid voltage is instantaneously dropped, the UPS appears to be overkill for voltage transient drops. The UPS is powered by the battery and the working time lasts for a long time. However, due to the shortcomings of the battery itself (regular maintenance and short life), the UPS needs to pay attention to the state of the battery during operation. The duration of the power system voltage drop is often very short (10ms ~ 60s), so the advantage of using supercapacitors in this case is more obvious than the UPS: its output current can rise to hundreds of amps with almost no delay, and the charging speed Fast, energy storage can be achieved in a few minutes, so it can be used in the next power failure [16]. Therefore, although the energy storage capacity of the supercapacitor can be maintained for a short time, when the usage time is about 1 min, it has an unparalleled advantage - 500,000 cycles, no need for care, and economy. In Singapore, ABB's dynamic voltage recovery device (DVR) using supercapacitor energy storage is installed in a 4MW semiconductor factory to achieve a low voltage span of 160ms.

Compared with batteries, super capacitors have the following characteristics:
a. Ultra-low series equivalent resistance (LOW ESR), power density (Power Density) is more than tens of times that of lithium-ion batteries, suitable for large current discharge, (a 4.7F capacitor can release instantaneous current more than 18A).
b. Long life, charging and discharging more than 500,000 times, 500 times that of Li-Ion battery, 1000 times that of Ni-MH and Ni-Cd batteries. If the super capacitor is charged and discharged 20 times a day, continuous use can reach 68. year.
c. It can be charged with large current, short charging and discharging time, simple requirements for charging circuit, no memory effect.
d. Maintenance free, sealable
e. The temperature range is wide -40 ° C ~ +70 ° C, the general battery is -20 ° C ~ 60 ° C.Coin Farad Capacitor suppliers
