摘要
不间断电源在可靠供电中扮演非常重要的角色,特别是随着各种政策法规的出台,对无谐波污染的绿色不间断电源装置的呼声越来越高。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。
The UPS plays a very important role in the reliable power supply, especially along with the policy laws and regulations appearing, so the call to the green UPS which has non- overtone pollution is higher and higher. The method of enhancing the input power factor in the online digital UPS is introduced： the power factor of the UPS approximates 1 and the total harmonic component reduces greatly by controlling the input current profile.
