Measurement of EMI on Fluorescent Electronic Ballast and Counter Analysis

형광등용 전자식 안정기의 EMI 대책

Requirements for high-efficiency equipment for energy saving are rapidly increasing recently keeping pace with development of digital and semiconductor technology. Accordingly, there are many changes and development in ballast. Ballast currently in use are Magnetic ballast (Coiled Type) and Electronic ballast. Electronic ballast produces incredible energy saving effect, but falls short of confidence instead. In addition, use at higher frequency through switching device creates Electromagnetic Interference (EMI) and high frequency. EMI creates low quality of equipment, damage in facilities and low productivity by leading miss operation of equipment, and interferes with surrounding machines. In this analysis I am going to examine characteristics of EMI on the Electronic ballast of FLR32SS one type pursuant to annex 3 of Electric Goods Technology Standard, and counter technology.
