摘要：近年來,由于電力電子器件的發(fā)展,變頻調(diào)速、逆變、斬波等新技術(shù)的應(yīng)用,電壓、電流的波形已不再是標(biāo)準(zhǔn)的正弦波或直流。傳統(tǒng)的互感器顯然已不適于對該波形的測量。因此,很多國家都相繼進(jìn)行了非接觸式電流電壓傳感器的研究開發(fā),其中尤以霍爾電流電壓傳感器被視為該項(xiàng)技術(shù)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、總結(jié)Summmary
在UPS電源系統(tǒng)中，閉環(huán)霍爾電流傳感器用于測量輸出電流，UPS控制器根據(jù)此電流進(jìn)行反饋控制，保證逆變電源正常工作。由于其響應(yīng)速度快，特別適用于計(jì)算機(jī)中的不間斷電源。
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.
