| 摘要 |
The present invention relates to a harmonic reduction apparatus, which uses a resonance zero phase sequence impedance for reducing a harmonics using a resonance of zero phase sequence impedance with respect to a zero phase sequence harmonics current which occurs in a three-phase multiple line for supplying an alternating current to a load, and in particular to an apparatus for reducing an impedance using a crossed coupling transformer (zigzag transformer) and a capacitor with respect to zero phase sequence harmonics generated from the side of a load and include into a electronic power system, an reducing zero phase sequence harmonics based on the crossed coupling transformer (zigzag transformer) by implementing an easier induction of the zero phase sequence harmonics. |
