Power converter

摘要

A power module includes a power module body portion and a wiring board. The power module body portion includes P-side semiconductor elements and N-side semiconductor elements, and a P-side terminal connection portion, a U-phase terminal connection portion, and an N-side terminal connection portion which establish electrical connection with the wiring board on an upper surface of the power module body portion and into which a current flows from the wiring board and from which a current flows to the wiring board.

1. A power converter comprising:
a power converter body portion; and a wiring board that is electrically connected to the power converter body portion, wherein the power converter body portion includes a power-conversion semiconductor element and a wiring board connection portion, the wiring board connection portion including a first wiring board connection portion and a second wiring board connection portion which establish electrical connection with the wiring board on an upper surface of the power converter body portion and into which a current flows from the wiring board and from which a current flows to the wiring board, and positions of the first wiring board connection portion and the second wiring board connection portion with respect to the power-conversion semiconductor element are set so that, in a case where a current flows from the wiring board into the power-conversion semiconductor element via one of the first wiring board connection portion and the second wiring board connection portion and then the current flows out toward the wiring board via the other of the first wiring board connection portion and the second wiring board connection portion, a direction in which a current that is to pass through the power-conversion semiconductor element flows is substantially opposite to a direction in which a current that has passed through the power-conversion semiconductor element flows, and flowing of the currents in substantially opposite directions enables cancelling out of changes in magnetic fluxes.
