| Abstract: |
| The work aims to enhance the driving operation reliability of xenon lamp for solar simulator, provide technical support for the development of solar simulator, and study the discharge characteristics of high power short arc xenon lamp for solar simulator.First, test method for discharge characteristics of high-power short arc xenon lamp for solar simulator was designed. Then through the theoretical calculation and practical tests, the influence of the initial current on the discharge characteristics of short arc xenon lamp was verified, and additional optimized circuit for short arc xenon lamp was adopted to improve discharge characteristics. Under the initial current of 70 A and 120 A, the current stability after the arc discharge current reached the current valley was respectively 1.8616 and 0.9867. After the addition of optimized circuit, the discharge characteristics of short arc xenon lamp were measured again, the initial current was reduced to 60 A and the stability was up to 0.5409.The improved circuit can basically achieve the ideal discharge state of short arc xenon lamp. It completes the optimization of the stable arc discharge current characteristic after the xenon lamp enters the current breakdown stage, greatly enhances the success ignition rate of xenon lamp, and provides experimental support for improving the reliability of solar simulator. |
