alternating current (AC)

基本解釋

At the moment, data centres perform many conversions between alternating current (AC) and direct current (DC).
時下，數(shù)據(jù)中心要在直流電和交流電之間頻繁轉(zhuǎn)換。
Alternating Current (AC) is electric current that alternates between a positive maximum value and a negative maximum value at a characteristic frequency, usually 50 or 60 cycles per second (Hertz).
交流，指電流在正負(fù)最大值之間以特定的頻率變動，通常頻率爲(wèi)50或60赫玆。

Following the vector control technique, the quick development of DTC makes itself a new high-powered Alternating Current (AC) driving technique paralleling to the vector control.
它是繼矢量控制技術(shù)之後，且與之竝行發(fā)展的一種新型的高性能的交流調(diào)速傳動的控制技術(shù)。

Inverters and microinverters convert the direct current (DC) power produced by solar panels into alternating current (AC) used in homes and businesses.
