alternating current (AC)

基本解释

At the moment, data centres perform many conversions between alternating current (AC) and direct current (DC).
时下，数据中心要在直流电和交流电之间频繁转换。
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，指电流在正负最大值之间以特定的频率变动，通常频率为50或60赫兹。

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.
它是继矢量控制技术之后，且与之并行发展的一种新型的高性能的交流调速传动的控制技术。

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