Among them , the action of the reactive current testing circuit is testing the reactive current component in the compensated object current 其中,無(wú)功電流檢測(cè)電路的作用是檢測(cè)出補(bǔ)償對(duì)象電流中的無(wú)功電流分量。
Three - phase four - wire apf with one - cycle control need not sense the three phase load currents or the three phase voltages , need not calculate the harmonics and reactive current components , as well as the use of any multipliers 單周控制三相四線制有源電力濾波器不需要檢測(cè)三相負(fù)載電流和三相電源電壓,不需要檢測(cè)諧波和無(wú)功電流,也不需要使用任何乘法器。
