Abstract

This paper dealt with the design and fabrication of a low frequency electronic ballast for ruh attracting lamps. The proposed electronic ballast was composed of a full-wave rectifier, a step don converter operated as a constant power controled current source, an inverter operated by 130 Hz square wave, and an ignition circuit. An acoustic resonance phenomenon of discharge lamps could be eliminated by application of 130 Hz square wave. Also, a circuit of high voltage pulse generation for lamp ignition was added to the ballast. From the experimental results, voltage and current of the lamp operated by the electronic ballast were estimated 132.5 V and 7.6 A, respectively. and the power consumption was about 1,000 W. The weight of the ballast, which is one of important advantages, was reduced to one-fifth of conventional magnetic ballasts.

본 논문은 저주파 구동형 집어등용 전자식 안정기의 설계 및 제작에 관하여 기술하였다. 제.안한 안정기는 전파 정류회로, 정전력형 전류원으로 동작하는 강압형 컨버터와 130Hz 구형파 발진의 인버터 및 재점등 보호회로로 구성하였다. 램프의 음향공명현상은 130Hz의 저주파 구형 펄스로 제거할 수 있었으며, 램프의 재점등을 위한 고전압 펄스 발생회로를 부가하였다. 실험결과로부터 본 안정기에 의해 구동되는 램프 전압과 전류는 각각 132.5V, 7.6A, 소비전력은 약 1,000 W이었다. 전자식 안정기의 가장 큰 이점으로 중량은 동일 용량의 자기식 안정기에 비해 약 1/5로 감소하였다.
