Embodiment 1
[0027] The distribution of the current intensity of the 9.5MHz common-mode current along the 10-meter-long cable in the electric vehicle is as follows: image 3 As shown in (a); after the 20 cm long common mode current suppressor is connected in series at the opening of the cable, the distribution of the current intensity of the 9.5 MHz common mode current along the 10 meter long cable is as follows image 3 As shown in (b), it can be seen that the common-mode current is significantly suppressed.
Embodiment 2
[0029] The distribution of the current intensity of the 5.0MHz common-mode current along the 10-meter-long cable in the electric vehicle is as follows: Figure 4 As shown in (a); after the 40 cm long common mode current suppressor is connected in series at the opening of the cable, the distribution of the current intensity of the 5.0MHz common mode current along the 10 meter long cable is as follows Figure 4 As shown in (b), it can be seen that the common mode current is also well suppressed.
