摘要
介绍了一种应用于高压大功率全频段调频式(FBFM)开关电源直流输出侧电磁干扰(EMI)滤波电路的设计方法。通过该方法,设计了一款应用于高压大功率FBFM开关电源直流输出侧EMI滤波电路。通过Saber仿真及实验验证了通过该方法所设计的EMI滤波器能有效降低直流输出侧的高频噪声,提高了直流电压的输出品质。
The design method of a electromagnetic interference(EMI) filter for DC output side of high voltage and high power full band frequency modulation(FBFM) switching power supply is introduced.Through this method,a EMI filtering circuit for DC output side of high voltage and high power FBFM switching power supply is designed.Through the Saber simulation and experiment, it is verified that the EMI filter designed by this method effectively reduces the high frequency noise of the DC output side, and improves the output quality of DC voltage.
