In-vehicle power conversion device

Abstract

To provide an on-vehicle power conversion device 1 configured to convert AC power inputted from an AC power source 2 to DC power, and supply the DC power to an on-vehicle battery.SOLUTION: An on-vehicle power conversion device 1 includes: a power conversion circuit 10; a frame ground FG that is grounded via a wire 4; a first filter circuit 11 that is provided between a positive input path A and a negative input path A' of AC power; and a second filter circuit 12 that is provided between a positive output path B and a negative output path B' of DC power. The first filter circuit 11 includes: a first capacitor C1 and a first ferrite bead FB1 that are connected in series between the positive input path A and the frame ground FG; and a second capacitor C2 and a second ferrite bead FB2 that are connected in series between the negative input path A' and the frame ground FG. The second filter circuit 12 includes: a third capacitor C3 that is connected between the positive output path B and the frame ground FG; and a fourth capacitor C4 that is connected between the negative output path B' and the frame ground FG.SELECTED DRAWING: Figure 1
