고조파 저감형 하이브리드 변압기의 성능시험

초록

Hybrid transformer means the distribution transformer, one of multi-function transformer equipped with theenhancement function of harmonics and unbalance. In other words, since existing transformer are equipped simply withtransformation function only, a separated electric facility should be additionally installed in order to reduce the mutualharmonics and unbalance. Meanwhile, since hybrid transformer can perform the reduction of harmonics and unbalance aswell as transformation function simultaneously through zigzag winding, it doesn’t need any additional electric facility. This study addressed the issue of developing and testing the performance of a generator that would reduce theharmonics supplied to the grid when grid-connected with the output of a photovoltaic inverter for photovoltaic generationsystem.
