摘　　要：通过对输入电流畸变和开关电源电路中瞬间尖峰脉冲对日常设备产生危害进行仔细分析 ,找出电源谐波产生的原因 ,对照利用谐波测试仪测试谐波对不同电视产生影响的各种数据反映 ,提出解决谐波干扰的具体措施 。This paper carefully analyses input electrical current aberration and instant pinnacle pulse in the switch power source circuit, which harmed daily equipment.The reason of causing harmonic contents in power source is found. In contrast to lots data measured in the test that how the harmonics affect different TV,the paper puts forward the measures for reducing the harmonic contents. It is useful for reference and guidance to solve the problems about harmonic immunity of the Electrical Apparatus.
