A power conversion apparatushas a configuration in which a plate-like bus-baris disposed vertically so that a width direction thereof is set in a vertical direction, electrically connected to positive electric potential of a battery and fixed to a resin caseto include a flat plate-like bus-bar body, to which positive electric potential of the battery is applied, and a voltage measuring terminaltobranched from the bus-bar body. The voltage measuring terminaltoincludes a projecting portionprojecting from the bus-bar body, an upright portionextending from the projecting portionupward toward a circuit board, and a measuring terminal portionthat is an upper part of the upright portionand electrically connected to the circuit board

Power conversion apparatus

A power conversion apparatus has a configuration in which plate-like bus-bars are laminated via an insulating material to define a pair of bus-bars. A laminated bus-bar, in which the pair of bus-bars is disposed vertically so that a width direction thereof is in a vertical direction, includes a pair of voltage measuring terminals that is correspondingly branched from a part of the pair of bus-bars to extend toward a circuit board. The pair of voltage measuring terminals is arranged symmetrically with respect to the pair of bus-bars to extend upward toward the circuit board, while extending in an intersecting direction intersecting with the pair of bus-bars, to be electrically connected to the circuit board.

A power converter includes a bus bar, a semiconductor device, a lead, and solder. The bus bar has a vertical wall. The semiconductor device includes an electrode. The lead has one end connected to the bus bar and another end connected to the semiconductor device to supply power from the bus bar to the electrode of the semiconductor device via the lead. The one end of the lead includes a bending part which is spaced away from the bus bar by a predetermined distance and which is inclined in a vertical downward direction. The vertical wall of the bus bar and the bending part are bonded to each other via the solder. The vertical wall extends in a substantially vertical direction to face the bending part.
