■产品概述productoverview


变频器制动时所产生的再生能量回馈到电网,并加以利用,但是整流单元是IGBT,会产生较多的高次谐波电流,进而会对电网污染。所以在变频器的
前端加上能量回馈电抗器和滤波器组合以改善电能质量。


The regenerative energy generated during the braking of the frequenoy converter is fed back tothe power grid and utilized,but therectifier uni is an IGBT,which generates a large amount of high-order harmonic curent,thereby polluting the power grid.So,anenergy feedback reactor and iter combination are added at thefrontend of the frequency converterto improve power quality.
