提高荧光灯电子镇流器效率的研究

荧光灯的发光效率与电源的频率存在一定的依赖关系，发光效率在一定频率范围内随电源的频率增大而升高，但是电子镇流器的效率随频率的提高而降低，所以需要综合地选择一个合适的工作频率，才能使灯管和镇流器整体的效率最高。本文深入研究了电子镇流器中各元件的参数性能对电子镇流器工作效率的影响，提出了减小荧光灯电子镇流器自身功耗的方法，其使荧光灯电子镇流器自身功耗降低1W以上，对于设计制造高性能电子镇流器具有一定的参考价值。

Research on Improving the Efficiency of Electronic Ballast for Fluorescent Lamps

Fluorescent efficacy is dependent on the power frequency to a certain extent. The efficacy increases with the power frequency increasing in a certain range, while the efficiency of electronic ballasts decreases. It is necessary to select a suitable operating frequency comprehensively in order to make the system efficiency reach the maximum. In this paper, the relation between parameters of each component in electronic ballast and ballast efficiency is researched in depth. Also the method of reducing the power consumption of electronic ballast for fluorescent lamps is proposed. This method can reduce more than one watt of power consumption, and has a certain reference value for the design and manufacture of high-performance electronic ballasts.
