전동기 구동용 인버터에서 유출되는 고조파의 특성 및 저감방안

초록

This paper deals with the harmonic distortion caused by using inverters for driving motors. Nowadays power conversion devices including inverter are widely used and harmonic problems are raised. Because of this phenomenon, harmonic reduction devices have been frequently used. We measured the current harmonics at input terminals of inverter with filters such as EMC filter and reactor. As a consequence, it was found that reactors are effective but EMC filters are rarely effective in reduction of current harmonics.
