| 摘 要： | 开关电源的电磁干扰是舰艇电磁兼容工程中的典型问题.针对舰艇电网上出现的低频传导干扰现象,着重探讨开关电源低频传导发射及其对电网的影响.详细分析了开关电源低频传导干扰的形成机理,并为开关电源建立了低频传导发射模型以计算电网上的低频谐波干扰.在此基础上,借助软件工具对开关电源的低频传导干扰进行模拟仿真,分析了流回到电源线上的传导发射电流以及谐波畸变情况,从而实现对开关电源低频传导干扰的数值预测. |
| 关 键 词： | 开关电源 电磁兼容 传导发射 谐波 |

| Abstract: | The EMI of the switching mode power supply(SMPS)is the typical problem in EMC engineering of ship. Aiming at the low frequency conducted interference phenomenon in electricity networks of ship,the low frequency conducted emission of SMPS and its influence on electricity networks is discussed. The conducted EMI formation mechanism of SMPS is analyzed,and a low frequency conducted emission model is established for computing the low frequency harmonic interference in electricity networks. Based on the model,th... |
| Keywords: | switching mode power supply EMC conducted emission harmonic |
