| Abstract: | 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. |
