汽车用氙气前照灯电子镇流器的设计

摘要

A novel electronic ballast for xenon high -intensity-discharge (HID) is designed and implemented based on PIC16F785 control. In view of the drawbacks of lower efficiency and lower reliability of the electronic ballast for HID, the sighl -chip control and planar power transformer and zero voltage switching(ZVS) and SMT technology improves reliability and 4% efficiency of the electronic ballast for HID. Experiment results testify the feasibility and effectiveness of this design.%采用PIC16F785单片机进行控制,设计并实现了一种新型的汽车用氙气前照灯镇流器.针对当前汽车用氙气前照灯镇流器产品效率低、可靠性差等方面的不足,采用单芯片控制、平面变压器、软开关和全贴片等技术,大幅度提高产品的可靠性,效率提高了4％.实验结果证明了该设计的可行性和有效性.
