본 논문에서는 최근 다양한 부하와 전원으로 인하여 전력전자장치의사용이 급증하고 있다. 그중 대표적인 회로인 정류회로에 대하여 모의아크 발생장치로 아크를 발생 하였을 때 출력부의 임피던스로 인하여 어떠한 영향을 미치는지를 전력전자의 관점에서 실험을 통하여 분석 및 검토하였다.

The monitoring technique for trace organic pollutants is developed to find the pollutant and solve the environmental accident by persuiting the effluent source. Twenty five samples of the inffluent, effluent and stream water were collected to apply the monitoring technique for trace organic pollutant in the Imjin liver. In Mumyung stream, the collected samples from pollutant source of the downstream are analyzed. The peak patterns of volatile organic compounds such as sulfur compounds, toluene and indene compounds agreed to the leather factory and the peak patterns of semivolatile organic compounds such as phosphate compounds agreed to the foundry. In Hyochon stream, the volatile organic compounds such as trichlorobenzene, naphthalene, benzene and toluene are detected in the main stream of the Shin stream. These peak patterns agreed to the effluent peaks of painting and textile manufacturing industries. Also, the peak patterns of semi-volatile organic compounds (phenol compounds and hydrocarbons of high boiling point) conformed to the furs manufacturing industry. In Sangpai stream, the collected samples from midstream of Sangpai stream are detected the trichlorobenzene and trihalomethans as volatile organic compounds. These characteristic organic pollutants are generally discharged from the textile & dyeing based on the established database. From these information, we found that the wastewater is discharged from two textile industries as the result of pursuit. The semi-volatile organic compounds, which are indole and phenol compounds, also accorded to the peak patterns of textile & dyeing.
