초록

본 논문에서는 전자파 장해 측정용 야외시험장과 전자파 내성 시험장인 GTEM 셀과의 상관계수를 이용하여 GTEM 셀에서 전자파 허용 기준을 제시하였다. 실험적인 상관계수를 도출하기 위해서 피시험 기기를 제작하였으며, 제작된 피시험 기기의 전기장 세기를 10 m 야외시험장과 GTEM 셀에서 측정하였다. 또한, GTEM 셀의 3방위법을 역변환함으로써 GTEM 셀에서 복사 전력에 대한 허용 기준을 도출하였다. GTEM 셀의 3방위법과 15방위법에 대한 이론치를 프로그램화 하였으며, 프로그램을 통한 결과 값과 시험장에서 측정한 값을 비교 분석하였다. GTEM 셀에서 전자파 허용 기준을 새롭게 제시함으로써 GTEM 셀이 야외시험장의 전자파 방사(EMI) 대체 시험장으로서 활용될 수 있음을 확인하였다.

This study is about the limits of GTEM cell using correlation factor between the OATS(Open area Test Site) and the GTEM cell. First, the field strengths at the 10 m distance OATS and in GTEM cell to obtain the experimental correlation factor are measured. Also, the EMI limits of radiated power are derived in GTEM cell as 3 position method is inversely transformed. The field strengths that calculated from theoretical models by 3 and 15 position methods are programmed and compared with measured data at the OATS. As the EMI limits of GTEM cell is newly defined, it will be use to substitute GTEM cell for OATS to efficiently measure EMI(Electromagnetic Interference).
