초록

비선형 부하는 고조파 발생원으로 고조파 전압원과 고조파 전류원의 두종류로 분류된다. 직렬동조필터는 개인용 컴퓨터 부하와 같이 직류 캐패시터가 있는 비선형 부하로 고조파 전압원에 매우 효과적으로 고조파를 저감시킨다. 병렬동조필터는 교류 구동장치와 같이 직류 리액터가 있는 비선형 부하로 고조파 전류원에 적합하다. 본 논문에서는 직렬 및 병렬 동조 필터의 고조파 저감 특성과 비교를 검토하고 실험하였다. 국제 고조파 관리 기준인 IEC 1000-3-2 으로 직렬 및 병렬 동조필터의 고조파 저감 효과를 평가하고자 한다.

This paper characterizes typical nonlinear loads into two types of harmonic sources, i.e., harmonic voltage source and harmonic current source. A series resonant filter is very effective in harmonic reduction for harmonic voltage source type of nonlinear loads such as personal computer loads with smoothing dc capacitors. A parallel resonant filter is suited for current source type of nonlinear loads such as ac drives with smoothing dc reactors. General compensation characteristics and comparison of series and parallel resonant filters are given analytically and experimentally. Compliance with IEC Std 1000-3-2 has been evaluated for limiting harmonic distortion.
