摘要：近年来,由于电力电子器件的发展,变频调速、逆变、斩波等新技术的应用,电压、电流的波形已不再是标准的正弦波或直流。传统的互感器显然已不适于对该波形的测量。因此,很多国家都相继进行了非接触式电流电压传感器的研究开发,其中尤以霍尔电流电压传感器被视为该项技术的代表。

Abstract: In recent years, due to the development of power electronic devices and the application of new technologies such as frequency converter, inverter and chopper, the waveform of voltage and current is no longer the standard sine wave or DC. The traditional CT is obviously not suitable for the measurement of the waveform. Therefore, many countries have carried out the research and development of non-contact current and voltage sensor, especially Hall current and voltage sensor is regarded as the representative of this technology.

4、总结Summmary

在UPS电源系统中，闭环霍尔电流传感器用于测量输出电流，UPS控制器根据此电流进行反馈控制，保证逆变电源正常工作。由于其响应速度快，特别适用于计算机中的不间断电源。

In the UPS power system, the closed-loop Hall current sensor is used to measure the output current, and the ups controller carries out feedback control according to the current to ensure the normal operation of the inverter. Because of its fast response speed, it is especially suitable for uninterruptible power supply in computer.
