TRANSFORMER FOR VEHICLE

PROBLEM TO BE SOLVED: To achieve countermeasures against induction nindrances for signals in various frequency bands by suppressing a harmonic current flowing out from a ground line. SOLUTION: In a transformer for vehicles, where a high-tension wiring 10a and a low-tension wiring 10b are wound around an iron core 9, and an electrostatic shielding plate 11 is disposed between both the windings 10a, 10b and is accommodated in a tank 8, and further the iron core 9, the electrostatic shielding plate 11, and the tank 8 are grounded via a car body 7, an iron core lead wire 13, at least connected with the iron core 9, is insulated from the tank 8 and is led to the outside of the tank 8. Further, an iron core impedance 15 is connected between the iron core lead wire 13 and the car body 7 outside of the tank 8. COPYRIGHT: (C)2004,JPO
