摘要
采用AltiumDesigner16设计并制备了某降压开关电源PCB样品。根据GJB151B-2013中的RE102测试要求,使用CST线缆、微波和设计工作室建立开关电源PCB及RE102测试环境的电磁仿真模型,探讨开关电源PCB的RE102仿真方法,仿真并实测开关电源PCB与线缆的辐射结果。开关电源PCB的RE102仿真与实测结果高度吻合,仿真方法正确。
PCB sample of a step-down switching power supply was designed and prepared by Altium Designer 16. According to the requirements of the RE102 test standard in GJB 151B-2013, the electromagnetic simulation model of switching power supply PCB and RE102 test environment are established by using CST cable, microwave and design studio. The RE102 simulation method of switching power supply PCB is discussed, and the radiation results of switching power supply PCB and the test cable are simulated and measured. The RE102 simulation of switching power supply PCB is highly consistent with the measured results, and the simulation method is correct.
