Abstract
This on-vehicle power conversion apparatus is provided with: a power conversion circuit to which DC power is inputted; and a noise reduction unit that is configured to reduce common-mode noise and normal-mode noise which are included in the DC power and that is provided to the input side of the power conversion circuit. The noise reduction unit is provided with: a core having a first core part and a second core part; a common-mode chalk coil having a first winding wire wound around the first core part and a second winding wire wound around the second coil part; and a smoothing capacitor that constitutes a low-pass filter circuit cooperatively with the common-mode chalk coil. The power conversion apparatus is further provided with a damping unit provided at a position intersecting the magnetic path of a magnetic flux leakage.
