| 摘 要： | 为了克服电网干扰对用电设备的破坏,目前广泛采用UPS为敏感用电设备供电。如何消除形形色色的干扰对用电设备造成的影响,为用电设备提供高可靠性、高质量的纯净电源,是各UPS厂商面对的问题。文章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,总的谐波分量大大减少。

| Abstract: | In order to overcome the destruction of the electrical network disturbance to the current collector,at present UPS is widely used as a sensitive power supply.How to eliminate the disturbance of the influence which creates to the current collector,provide the pure power source for the current collector,is a problem which each UPS manufacturer faces.This article introduces the method of enhancing the power input factor in the digitized UPS,by controlling the input current profile,the power factor approximates 1,the total harmonic component reduces greatly. |
