車載用電力変換装置
Document Type and Number:
Japanese Patent JP5922516
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that flowing currents of power conductors 24a, 24b, which connect a power conversion circuit 6 incorporating a switching element with a power source, are intermittently turned on and off and thus noise occurs in control lines 20a, 20b switching the state of the switching element and may cause a malfunction of the power conversion circuit 6.SOLUTION: At least parts of power conductors 24a, 24b are enclosed by a shield conductor 40. One end part of the shield conductor 40 is connected with a housing 4. The other end part of the shield conductor 40 is connected with a ground conductor 8 to which an electric power conversion circuit 6 is grounded. A capacitor 46 is provided between the housing 4 and the ground conductor 8. This structure prevents noise from occurring in control lines 20a, 20b.
