摘　　要：提出了一种简单易行的晶闸管控制荧光灯调光方法。给出了新型电子镇流器的电路结构,重点讨论了提高其功率因数、功率变换及可变调光的工作机理。该新型电子镇流器通过在调光器中引入电源电压信号处理装置,使电源进线由原来单纯传递电能,转变为包含控制信号,在原有接线方式的基础上实现了亮度可调。样机实验表明,该电子镇流器具有一定的应用价值。This paper proposes a simply and feasible dimming method of the fluorescent lamp.A new high power factor dimmable electronic ballast circuits is designed, the principle of high power factor dimmable electronic ballast to improve power factor, DC/AC energy transfer and variable dimming is described.Through the management of the voltage, electrical power and dimming signal are transferred by incoming wire at the same time, so the connection is simplified. The experimental results show that electronic ballast have good electronic performance.
