| 摘 要： | HID氙气灯必须工作在恒定功率条件下,通常采用功率误差检测环路来实现。在分析了35 W车用HID氙气灯工作特性和市场上HID氙气灯安定器设计特点的基础上,提出了一种新颖的HID安定器的设计方案,其特点是同时采用了数字和模拟两个功率误差检测环路。实验表明,采用以此结构设计的安定器既保证了很好的瞬态特性,又保证了进入稳态后输出功率的稳定性。

| Abstract: | HID Xenon gas lamp must operate under constant power supplying.Normally it is realized with power error detecting loop.this paper proposes a new design scheme for HID Xenon gas lamp ballast under analyzing the characteristic of 35 W HID Xenon gas lamp and the design speciality of its ballast in market,which adopts two loops of digital and analog power error detecting feedback.Test results show that,the ballast designed by this scheme can guarantee not only a very good instantaneous status characteristic,but also the output power stability after the lamp entering into the steady state. |
