초록

최근 에너지의 효율적인 사용을 위해 제작되어 상용화되고 있는 전력변환장치는 기기 특성상 기본파의 n배 주파수를 갖는 고조파를 발생시키고 있다. 이렇게 발생된 고조파는 기본 정현파를 대상으로 제작된 여타 기기의 작동에 악영향을 끼치므로 반드시 제거해야할 요소로 문제시되고 있다. 본 논문에서는 현재 정보화 시대를 맞이하여 증가되고 있는 PC를 대상으로 고조파 발생량을 측정$.$분석 하였으며 그에 따른 가장 효과적인 고조파 저감대책을 제시하였다.

Recently many kinds of power transducers have been commercially used to increase the energy efficiency. However, those devices unavoidably produce the harmonics having an integral frequency of fundamental waves. The harmonics should be removed since they have negative effects on the other devices based on fundamental sine waves. As the current information technology makes the PCs more widespread, it is essential to study the harmonics that they produce. In this paper the harmonic generation of a PC has been measured and analyzed. Additionally, the most efficient way of reducing the harmonics has been proposed.
