Abstract

본 발명은 직렬공진을 이용한 형광등용 전자식 스타터로서, 형광등 각 필라멘트가 전원전압의 음전압에 의해서 제2게이트구동부에 의해 트리거되는 제2반도체스위치에 의해 예열되게 하고, 전원전압의 양(+)전압에 의해서 제1게이트구동부에 의해 제1반도체스위치를 트리거시킬때 안정기의 인덕터와 콘덴서의 LC직렬공진으로 인한 전압펄스를 제공하여 형광등을 깜박 거림없이 점등시킬 수 있도록 한다.The present invention relates to an electronic starter for fluorescent lamps using series resonance, wherein each fluorescent lamp filament is preheated by a second semiconductor switch triggered by the second gate driver by a negative voltage of the power supply voltage, and a positive voltage of the power supply voltage. By triggering the first semiconductor switch by the first gate driver by providing a voltage pulse due to the LC series resonance of the ballast inductor and capacitor to enable the fluorescent lamp to light up without flicker.
