    • PROBLEM TO BE SOLVED: To suppress noise on the side of a battery rather than a DC/DC converter, and to suppress the propagation of noise to a vehicle body. SOLUTION: The terminal of a DC/DC converter 26 is connected with the positive electrode of a low-voltage battery 24 by a core wire 32 of a shield line 30, and a housing 27, to which the DC/DC converter 26 has been grounded, is connected with the negative electrode of the low-voltage battery 24 by a shield section 34 of the shield line 30 with approximately the same impedance as the core wire 32. After that, a high impedance member 40 having higher impedance than the shield section 34 is disposed between the negative electrode of the low-voltage battery 24 and a vehicle body 28. As a result, common-mode noise of a low-voltage system can be suppressed, and the propagation of noise current to the vehicle body 28 can be also suppressed. COPYRIGHT: (C)2011,JPO&INPIT
