使用超級(jí)電容器的電壓穩(wěn)定

　　當(dāng)電驅(qū)動(dòng)機(jī)器啟動(dòng)時(shí)，它可能需要很高的電流從電源的一個(gè)短的時(shí)間內(nèi)。這種電流的結(jié)果往往是一個(gè)不可接受的電壓降，由于在電源網(wǎng)絡(luò)中的阻抗。這種電壓降可能導(dǎo)致連接到同一電網(wǎng)的其他設(shè)備的故障。因此，它是希望采取措施，以穩(wěn)定電壓在機(jī)器啟動(dòng)或其他類(lèi)似的事件，這將導(dǎo)致短期電壓瞬變。

　　能源儲(chǔ)存技術(shù)，如電池已被提出來(lái)解決這些電壓穩(wěn)定問(wèn)題。雖然電池可以?xún)?chǔ)存和釋放大量的能量在延長(zhǎng)的時(shí)間段，他們有困難，提供短期的高功率水平所需的電壓穩(wěn)定。此外，電池充電緩慢，在某些應(yīng)用中，它們的循環(huán)壽命短得多，通常不到一年或兩年。此外，電池在寒冷的天氣不好。這些因素限制了可接受的電池應(yīng)用電壓穩(wěn)定。

　　Notice that the machine start is a short process， usually lasting less than a few seconds. During this process， a large amount of power is required. Ultracapacitors， which can economically supply high currents and deliver large amounts of power in time frames as long as a few minutes， can thus act as a supplemental power supply to stabilize the network voltage during the start of a machine. Therefore， the main power supply will be minimally affected. This means that other equipment connected to the main power supply will not be exposed to low voltage and be able to function normally.
