摘　　要：简述了金卤灯的电气特性、声共振现象的产生机理及解决方法。采用不同于传统模拟控制方式的数字控制方式,分段控制金卤灯的4个运行阶段,避免了声共振现象的产生,设计出了性能参数达到较高水平的低频方波金卤灯电子镇流器。Electrical characteristics and generation mechanism and solutions of acoustic resonance of metal halide lamp are described briefly.Instead of the traditional analog control mode,a digital control mode is used to control the four running stages of metal halide lamp step by step to avoid causing the acoustic resonance phenomenon.In this way,the low frequency square wave electronic ballasts for metal halide lamp which have higher performance parameters are developed successfully.
