摘要
现行电子镇流器与工频电感镇流器一样,还是依赖电感的限流作用来维持荧光灯的正常工作。工作中的电感既有电磁辐射,又要消耗一定的电能。为此,提出了运用电容器的充放电来维持荧光屏灯工作的新方法,详细讨论了各元件的选取,给出了一种新型荧光灯电子镇流器。进一步降低了电子镇流器的耗能及生产成本,为电子镇流器的设计开辟了一条新途径。试验结果证明了该方法的正确性及可行性。
Existing electronic ballasts alike to the power frequency inductance ballasts depend on the inductance current limit role to maintain the normal operation of the fluorescent lamp.Whatever inductance, the work would emit the electromagneie radiation and consume some power.To solve this problem, the use of charge-discharge capacitors is suggested to maintain a new fluorescent lamp operating.The selection of the components is discussed and a new type of fluorescent lamp electronic ballasts is provided.In this way,the energy consumption of electronic ballasts and production costs are further reduced,and a new way for the design of electronic ballasts is opened up.Test results prove the correctness of the method and feasibility.
