Secondly, according to the character of this kind of harmonic, the solutions of power filter are deeply analyzed and an optimized topology for series connected hybrid power filter is obtained. by pwm technique, midfrequency transformer and the principle of the magnetomotive force ( mmf ) compensation, the problem to the transfer of the low - frequency harmonic power compensatory signal in the series apf is solved, in technique
其次，針對acem系統特有的「電源諧波」特性，深入分析了濾波器方案，得到了一種適用於acem系統諧波抑制的串聯混合型有源電力濾波器優化拓撲結構，並採用了pwm調制技術、中頻注入變壓器和磁勢補償原理有效地解決了串聯apf中低頻諧波功率補償信號傳輸的難題。
