Abstract: In an electric power conversion apparatus, a semiconductor module-cooler unit includes a semiconductor module and a cooler that has cooling pipes stacked with the semiconductor module in a stacking direction. A flow path forming component includes an electronic component main body and has an in-component flow path formed therein. A case receives both the semiconductor module-cooler unit and the flow path forming component therein. A pressure-applying member is arranged in the case to apply pressure to the semiconductor module-cooler unit from a rear side toward a front side in the stacking direction. Moreover, the flow path forming component is fixed to the case. The pressure-applying member, the semiconductor module-cooler unit and the flow path forming component are arranged in alignment with each other in the stacking direction. An in-cooler flow path formed in the cooler and the in-component flow path are fluidically connected with each other in the stacking direction.

Abstract: An electric power conversion apparatus includes at least one semiconductor module, a capacitor, a pair of positive and negative busbars and an insulator. The positive busbar includes a positive busbar base protruding from the capacitor in a Y direction and at least one positive busbar terminal extending perpendicular to an X direction. The negative busbar includes a negative busbar base protruding from the capacitor in the Y direction and at least one negative busbar terminal extending perpendicular to the X direction. The positive and negative busbar bases are arranged to have their major surfaces facing each other in a Z direction. The positive and negative busbar terminals at least partially overlap each other in the X direction with the insulator interposed therebetween. The at least one semiconductor module has a pair of positive and negative power terminals connected respectively to the positive and negative busbar terminals.

Abstract: A power converter includes a stack of a plurality of semiconductor modules, each of which incorporates semiconductor elements, and a plurality of cooling conduits, though each of which a coolant flows to cool the semiconductor modules, at least one electronic component electrically connected to the semiconductor modules, and a cooling plate for cooling the at least one electronic component. The stack, the at least one electronic component, and the cooling plate are arranged in a stacking direction of the stack. The cooling plate is connected to the cooling conduits and has an intra-plate pathway formed therein thorough which the coolant flows in a direction perpendicular to the stacking direction. The cooling plate has a larger area than each cooling conduit when viewed from the stacking direction.

Abstract: An electric power converter includes a semiconductor module constituting a power conversion circuit, a capacitor electrically connected to the semiconductor module, and a cooling member for cooling the capacitor. The capacitor includes an element body provided with internal electrode, and a pair of end-face-electrodes provided on both end faces of the element body and connected to the internal electrode. The pair of end-face-electrodes are connected with a pair of bus bars, respectively, in a manner of surface contact. The capacitor is disposed in a state where one of the pair of end-face-electrodes is facing the cooling member. The end-face-electrode facing the cooling member is in contact with the cooling member via the bus bar.
