摘　　要：摘要：抑制“声共振”和提高电光转换效率是HID灯电子镇流器的关键技术，本文的研究方向是将HID灯的工作频率提高至远离“声共振”的概率窗口之外，使灯在整个工作寿命期间内，灯的“声共振”及闪烁现象不再发生同时．由于电路设计采用高频“二阶变换”，使电光转换效率和可靠性有所提高，制作成本也大大降低。How to restrain the ＂acoustic resonauce＂ and impprove light efficiency are two most key technology of HID lamp electronic ballast .the research direction of this paper is boosting working frequency up to far away from the high probability of ＂acoustic resonance＂ ocour window, keep HID lamp in whole period of lifetime don＇ t have ＂acoustic resonance＂ and blinking happen anymore.owing to ＂second order transform＂ is designed, so that it can be got higher efficiency of electricity to light convert and the circuit operation reliability are improved as well. tested result and engi,wering case verification that research direction is （ully validity.
