交流电源

First, this paper briefly presented the construction of the software and hardware system of the ATE8000- 1 integrated test stand, and the monitoring circuit designs of alternating current power supply used voltage for this test stand.

文中首先简要介绍了ATE8000-1综合测试台系统的软硬件结构和总体方案，设计出了该测试台交流电源输出电压的监控电路。

The three-phase AC power phase sequence to identify and phase sequence control in industrial and agricultural production is of great significance.

三相交流电源的相序识别与相序控制在工农业生产中具有重要的意义。

The coil has enough inductance that when 220V 60Hz AC flow through it, they only draw 5A or so of current.

线圈有足够大的感抗，当220V/60Hz的交流电源接上时，只有5A左右的电流流过。

The basic components of an induction heating system are an AC power supply, induction coil, and work piece.

一个感应加热系统的基本构成是一个交流电源，感应线圈和工件。

Induction heating system elements, including induction coil, an AC power source and the workpiece.

感应加热系统的基本组成包括感应线圈、交流电源和工件。

What we need is a waveform-less voltage, otherwise we'd hear the twice mains frequency waveform.

但我们需要的是没有波形的电压，否则我们会听到交流电源频率两倍的声波，以及大量失真。

This produces a waveform of one polarity operating at a frequency twice that of the mains supply.

经过整流后得到的是一个频率为交流电源两倍的单极波形。
