摘　　要：脉冲氙灯因光谱与太阳光最为相近,常用于太阳能电池的性能测试。脉冲氙灯电源是保证脉冲氙灯可靠工作、提高光电转换效率的关键因素。为解决传统脉冲氙灯电源体积大、噪声干扰大、可靠性低等问题,设计了一款高可靠的脉冲氙灯电源,电源采用交错并联Buck电路构成的脉冲发生电路有效减小了输出纹波,采用改进型嵌套工作时序的数字控制方案提高了脉冲氙灯工作的可靠性。通过搭建实验样机并进行测试研究,结果表明所设计的脉冲电源可以使脉冲氙灯百分百点亮并能稳定工作。Pulsed xenon lamp is often used for performance testing of solar cells because its spectrum is most similar to sunlight.The pulsed xenon lamp power supply is the key factor to ensure the reliable operation of the pulsed xenon lamp and improve the photoelectric conversion efficiency.In order to solve the problems of the traditional pulsed xenon lamp power supply with large volume,large noise interference and low reliability,a highreliability pulsed xenon lamp power supply was designed.Staggered parallel Buck was adopted to reduce the output ripple,and the digital control scheme of the improved nested working sequence was used to improve the working reliability of the pulsed xenon lamp.By building an experimental prototype and testing,it is proved that the pulsed power supply can make the pulsed xenon lamp light up 100%and keep working stably.
