摘要
长期以来,不论是UPS的供应商还是用户,对如何提高UPS输入功率因数一直非常关注。介绍了数字在线不间断电源中提高输入功率因数的方法,通过实时控制输入电流的波形,该UPS的功率因数近似为1,使总的谐波分量大大减少,从而为用电设备提供了高可靠性、高质量的纯净电源。
Since long ago, no matter the UPS supplier or the user often discusses how to enhance the UPS power input factor. In this article, the method of enhancing the power input factor in the digitized UPS is introduced. By controlling the input current profile, the power factor approximates 1, the total harmonic component reduces greatly, thus redundant reliability,high grade pure power source for the current collector is provided.
