power in alternating-current circuits
解釋
交流功率-
The rectifier scheme that direct current supplying with power electronic equipment is obtained by alternating current being rectified is widely applied in power electronics field. however, the rectifying circuits result in input current distortion, input power factor greatly decrease
從電網獲取交流電經整流后為設備提供直流電是電力電子技術中應用極為廣泛的一種整流方案,然而由這種整流方案設計的電路使輸入電流產生嚴重的畸變,其諧波電流嚴重污染了電網,輸入端功率因數大大下降。
