摘　　要：针对机壳缝隙、电源线、信号线等引起的开关电源辐射发射问题,提出了简洁的干扰源判定方法,分别采取了套磁珠、减小缝隙尺寸、叠层走线等整改措施。整改后,测试结果符合标准要求。For radiated emission problems of switching-mode power supply caused by chassis slot, power lines, signal lines and so on, some simple methods for determining the source of interference are proposed. By using a set of beads, reducing the gap size, stack traces and other corrective measures, the test results could meet the standard requirements.
