수동역률 개선회로를 이용한 110/220V 겸용 정출력 안정기 개발

The development of 110/220V alternative static output ballast by using passive power factor correction circuit

In this paper, we propose the passive PFC(Power Factor Correction) circuit of an electronic ballast with the constant power the detection circuit for 110 or 220 volt. The proposed PFC circuit is composed with the modified dither circuit and the input voltage detection circuit. We have concluded that the proposed method is the attractive method to improve of power factor for the electronic ballast with the input voltage regulation and it is a similar experimental results with other active power factor correction method using other PWM ICs.
