| 摘 要： | 以往对强激光脉冲电源的电磁兼容性设计一般以经验性为主，难以确保电源的稳定性和可靠性。基于电源主体结构，提出一种定量分析和计算强电磁干扰的方法。对传导干扰的仿真和现场测试表明，机架上每米的地电位差小于10 V，机壳外的准静态磁场低于0.16×10-4T。测试和计算结果表明，电源电磁兼容性符合设计要求。

| Abstract: | Conventional methods for electromagnetic compatibility (EMC) design of high power supplies are mostly based on experience. It can not insure the stability and reliability of the supply. A method was proposed to quantitatively analyse the electromagnetic interference (EMI) according to the main structure of the supply. The conductive interference of the supply was simulated and measured in a practical supply, and the ground potential difference is less than 10 V (corresponding to unit of the enclosure). The quasi-static magnetic field as well as shielding efficiency is calculated, and the magnetic field outside the supply is less than 0.16×10 -4 T. The results of both calculation and measurement indicate that performance of EMC of the supply can measure up to the design criterion. |
