摘要
基于UC3842设计了一种特种灯开关电源装置。通过UC3842的电流脉宽调制功能实现对特种灯的引燃以及稳定供电,附加了外围保护电路,使电源模块自身具备过流、过压、过热等保护功能,抗电磁干扰能力强。试验过程选用2.5、3.3 kW两组长弧氙灯灯阵作为特种灯源进行测试。试验数据表明,该电源较好地保证了长弧氙灯的正常工作要求。
Based on UC3842 chip,a device of switching power supply was designed for a special lamp.It could carry out electric supplying ligniting and stability for the light by function of UC3842 PWM,adding outskirt protection for circuit,so that the device itself possessed the protected function of over-current,over-voltage,and o-ver-temperature.It also had the quality of anti-EMI.The test was conducted through two groups of long-arc xenon as the power supply with 2.5 kW and 3.3 kW.The data showed the assurance for the demand of the work.
