PROBLEM TO BE SOLVED: To provide a power conversion device in which a large inductive noise current is hard to mix into an external terminal.SOLUTION: A power conversion device 1 includes a power conversion circuit 10, a metal case 4, an external terminal 2, and two capacitors 3a and 3b. Each capacitor 3 has one electrode 31 electrically connected to the external terminal 2 and the other electrode 32 electrically connected to the case 4. A loop L through which a current flows is formed by the two capacitors 3a and 3b, the external terminal 2, and the case 4. An AC magnetic field H is generated from a part of the power conversion circuit 10. In the loop L, two regions of a first region S1 and a second region S2 exist through which the magnetic flux Φ of the AC magnetic field H penetrates. The directions of the magnetic flux Φ penetrating through the two regions S1 and S2 are opposite to each other. |
