A passive electromagnetic interference (EMI) filter can effectively suppress the conducted EMI of an on-board DC-DC converter at the cost of increasing the volume and cost of equipment, which runs counter to the original intention of high-power density design of electronic equipment. The suppression of conducted EMI by the combination of spread spectrum modulation and the filter can effectively reduce EMI and the filter volume as well. First, the method and process of EMI filter design are studied. Second, the principle of reducing EMI by spread spectrum modulation is analyzed. Combined with the calculation method for filter cut-off frequency, the optimal spread spectrum parameters are calculated, which increases the cut-off frequency in the design of a common-mode choke coil and effectively reduces the filter size. Finally, experimental results show that the spread spectrum modulation combined with the filter has a good suppression effect on the EMI of the on-board DC-DC converter, and the volumes of a compact common-mode choke coil and a filter after the spread spectrum modulation are reduced by 63% and 44% respectively compared with those of a common-mode choke coil and a filter used in the fixed frequency modulation.

无源电磁干扰EMI(electromagnetic interference)滤波器能够有效抑制车载变换器的传导电磁干扰,但会增加设备的体积与成本,这与电子设备高功率密度设计的初衷背道而驰。将扩频调制与滤波器结合抑制变换器传导电磁干扰,可在有效降低电磁干扰的同时减小滤波器体积。首先研究了电磁干扰滤波器设计的方法与流程;其次分析了扩频调制降低电磁干扰的原理,结合滤波器截止频率的计算方法,计算得到最优的扩频参数,增大了共模扼流圈设计中的截止频率,从而有效减小滤波器的尺寸;最后通过实验验证了扩频结合滤波器对车载变换器电磁干扰具有良好的抑制效果,并对比发现经过扩频调制后的紧凑型共模扼流圈和滤波器的体积相比于定频调制时使用的共模扼流圈和滤波器分别减小了63%和44%。

无源电磁干扰EMI(electromagnetic interference)滤波器能够有效抑制车载变换器的传导电磁干扰,但会增加设备的体积与成本,这与电子设备高功率密度设计的初衷背道而驰。将扩频调制与滤波器结合抑制变换器传导电磁干扰,可在有效降低电磁干扰的同时减小滤波器体积。首先研究了电磁干扰滤波器设计的方法与流程;其次分析了扩频调制降低电磁干扰的原理,结合滤波器截止频率的计算方法,计算得到最优的扩频参数,增大了共模扼流圈设计中的截止频率,从而有效减小滤波器的尺寸;最后通过实验验证了扩频结合滤波器对车载变换器电磁干扰具有良好的抑制效果,并对比发现经过扩频调制后的紧凑型共模扼流圈和滤波器的体积相比于定频调制时使用的共模扼流圈和滤波器分别减小了63%和44%。

A passive electromagnetic interference (EMI) filter can effectively suppress the conducted EMI of an on-board DC-DC converter at the cost of increasing the volume and cost of equipment, which runs counter to the original intention of high-power density design of electronic equipment. The suppression of conducted EMI by the combination of spread spectrum modulation and the filter can effectively reduce EMI and the filter volume as well. First, the method and process of EMI filter design are studied. Second, the principle of reducing EMI by spread spectrum modulation is analyzed. Combined with the calculation method for filter cut-off frequency, the optimal spread spectrum parameters are calculated, which increases the cut-off frequency in the design of a common-mode choke coil and effectively reduces the filter size. Finally, experimental results show that the spread spectrum modulation combined with the filter has a good suppression effect on the EMI of the on-board DC-DC converter, and the volumes of a compact common-mode choke coil and a filter after the spread spectrum modulation are reduced by 63% and 44% respectively compared with those of a common-mode choke coil and a filter used in the fixed frequency modulation.
